Mid-Winter Mid-Night Satellite

While video recording the star Tycho 1311-1818-1 in Taurus on a very cold Thursday evening last week (-4° F) in the hope that asteroid 126561 (2002 CF105) would pass in front of it (it didn’t), I was surprised and delighted to serendipitously record a very slow moving Earth-orbiting satellite crossing the field.  Now, in order to see a satellite, it must be illuminated by sunlight.  But to see any satellite during the first week of January only 10 minutes before local midnight, it must be very far from the Earth indeed (more on that later).

Here’s a video of the event showing its complete traversal of the field of view:

Slow-Moving Satellite

I’m hoping that one of the good people that frequent the satellite observers’ forum SeeSat-L will be able to identify this unusual object.  Requisite to that, of course, are two precise positions at two precise times and the observer’s location.

A very useful online tool provided by the Department of Physics at Virginia Tech allows one to input the right ascension, declination, and x-y coordinates of between 4 and 10 known objects, and it does an astrometric solution across the field so you can determine the right ascension and declination of an unknown object.

Using Guide 9.1, Limovie, and this tool, I determined the following:

At 5 Jan 2018 5:42:58.122 UT, the satellite was located at:
5h45m48.14s +21°45’17.5″ (apparent coordinates, epoch of date).

At 5 Jan 2018 5:50:22.931 UT, the satellite was located at:
5h46m53.98s +21°48’06.3″ (apparent coordinates, epoch of date).

Observer Location: 42°57’36.9″N, 90°08’31.1″ W, 390 m.

Using the satellite coordinates above, and the angular separation calculator kindly provided by the Indian Institute of Astrophysics, we find that the satellite traversed just 0.2590° in 0.1236 hours.  That’s 2.095° per hour, or only about four moon diameters in an hour!

Surely, this satellite must be way out there.  How far?  To determine that, I did a couple of what we used to call during my college physics days “back-of-the-envelope” (BOTEC) calculations.  These are rough approximations—using simplifying assumptions—that should get you to an answer that is at least the right order of magnitude.

If we can estimate the orbital angular velocity of the satellite, we can determine its orbital period, and if we could determine that, we can calculate it orbital distance.  Now, we don’t know yet if this satellite is in a near-circular or highly-elliptical orbit.  If the satellite is an a highly-elliptical orbit and we observe it near apogee, its angular velocity will be somewhat slower than the angular velocity of a circular orbit at that same distance.  If we observe it near perigee, then its angular velocity will be somewhat faster that the angular velocity of a circular orbit at that same distance.  First simplifying assumption: let’s assume a circular orbit.

The next simplifying assumptions are that (1) the satellite passes through the observer’s zenith, and (2) the distance to the satellite is large in comparison to the radius of the Earth.  At the time of observation, the satellite was at an altitude between 65° and 66° above the horizon.  Not quite the zenith, but maybe close enough.

First, we need to compensate for the fact that the observer’s location on the surface of the Earth is moving in the same direction (along right ascension) as the satellite is orbiting (eastward) as the Earth rotates.  We need to add the Earth’s rotational velocity to the right ascension component of the satellite’s velocity to get its true angular velocity relative to the center of the Earth.  This of course assumes that the radius of the Earth is small compared to the distance to the satellite.

During the 0.1236 hours we observed the satellite, it moved 0.2743° eastward in right ascension and 0.0469° northward in declination.  We now need to add a portion of the Earth’s angular velocity to the right ascension component of the satellite’s angular velocity.  If the satellite were at the north celestial pole, the amount we would add would be zero.  If, on the other hand, the satellite were on the celestial equator, we would add the full amount.  Since cos 90° is 0 and cos 0° is 1, let’s add the Earth’s rotational angular velocity times the cosine of the satellite’s declination to the right ascension component of the satellite’s angular velocity.

The Earth turns through 360° in one mean sidereal day (23h 56m 04s = 86,164s).  That’s 1.8591° during the 0.1236 hours we observed the satellite.  Taking that times the average declination of the satellite during the observation time, we get 1.8591° cos 21.7783° =1.7264°.  Adding this to the 0.2743° the satellite moved in right ascension, we get new components for the satellite’s angular displacement of 0.2743° + 1.7264° = 2.0007° in right ascension and 0.0469° in declination.  This gives us the “true” angular displacement for the satellite of

This is a motion of about 16.19° per hour, giving us a rough orbital period of 22.235 hours or 80,045 seconds.

Using Newton’s form of Kepler’s Third Law to calculate the orbital semi-major axis, we get (as a very rough estimate):

where G is the gravitational constant, M is the mass of the Earth in kg, and P is the satellite’s orbital period in seconds.

Geosynchronous satellites have an orbital radius of 42,164 km, so our mystery satellite is almost as far out as the geosynchronous satellites.  If it were further, the satellite would have been moving westward across our field of view, not eastward.

Admittedly, this is a lot of hand waving and is almost certainly wrong, but perhaps it gets us reasonably close to the right answer.

Now, let’s consider the shadow of the Earth to give us another estimate of the satellite’s distance.

At the time of observation, the Sun was located at 19h04m23s -22°36’40”.  The anti-solar point, which is the center of the Earth’s shadow cone, was then located at 7h04m23s +22°36’40”.   That is only 18.1° from the satellite.  The Sun’s angular diameter at that time was 32.5 arcminutes.  In order for the satellite to not be shadowed by the Earth, the angular diameter of the Earth as seen from the satellite must be less thanThe distance from the center of the Earth at which the Earth subtends an angle of 18.6° is given bySo, using this method, the satellite must be at an orbital radius of at least 38,905 km to be outside the Earth’s umbral shadow cone.

Now, on to something less speculative: the varying brightness of the satellite.  I used Limovie to track the satellite across most of the field and got the following light curve.

At first blush, it appears the satellite is tumbling with a period of around 51.2s.  But a closer inspection reveals that a larger amplitude is followed by a smaller amplitude is followed by a larger amplitude, and so on.  So the tumbling period looks to me to be more like 102.4s.  The mean (unfiltered) magnitude of the satellite looks to be around 11.8m, but ranging between 10.7m and 13.0m.  Thus the amplitude is around 2.3 magnitudes.  You will find the raw data here.

Update January 10, 2018

Alain Figer, French astronomer and satellite enthusiast, was kind enough to identify this object for me.  Alain writes, “At first glance I noticed, using Calsky, that Falcon 9 rocket, 2017-025B, #42699, might be your satellite…From the MMT data (astroguard russian site) 2017-025B rotation period was measured at 89.55s on 13 OCT 2017.  That figure seems to me in rather good agreement with yours at 102.4s, since the rotation period of this rocket might be quickly lengthening, a rather classical behaviour for such newly launched rockets.”  Alain goes on to say, “For estimating the satellite altitude from your own observations you have to consider its highly eccentric elliptical orbit.”  Thank you, Alain!

After I got home from work this evening, I began thinking, “Hmm, Guide is such an amazing program, maybe it can show me accurate satellite positions as well.”  Turns out, it can!  After downloading the current orbital elements for all satellites and turning on the satellite display, I was able to confirm Alain’s determination that this object is indeed Falcon 9 rocket body 2017-025B.

SpaceX launched the Inmarsat-5 F4 commercial communications satellite from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida using a Falcon 9 rocket on May 15, 2017.  Here are some pictures and a video of that launch.

The Falcon 9 rocket body currently orbits the Earth once every 23h21m19s in a highly-elliptical orbit (e=0.8358) that ranges from a perigee height of 432.4 km to an apogee height of 69,783 km.  During the time of observation, its range (i.e. distance from me, the observer) went from 64,388 km to 64,028 km.  The semi-major axis of its orbit is 41,481 km which is 3.3% higher than my (lucky) estimate above.  The shadow criterion of > 38,905 km is met as well.

Orbital inclination 25.6 degrees

Meteor Shower Calendar 2018

Here’s our meteor shower calendar for 2018.  It is sourced from the IMO’s Working List of Visual Meteor Showers (https://www.imo.net/files/meteor-shower/cal2018.pdf, Table 5, p. 25).

Each meteor shower is identified using its three-character IAU meteor shower code.  Codes are bold on the date of maximum, and one day either side of maximum.

Here’s a printable PDF file of the meteor shower calendar shown below:

The Good Old Days of Astronomy…

Those of you who grew up in the 1950s and 1960s as I did will especially delight in reading the July 7, 2007 entry of Uncle Rod’s Astro Blog, courtesy of Alabama astronomer Rod Mollise.  What a hoot!

And here’s a note from Phil Harrington’s website about Celestron’s ads in the 1990s: “It must be good to be an amateur astronomer in California, judging by the ads run by Celestron over the years…Yup, just another typical club star party, right?”  Photo montage by Rod Mollise.

Plastic Recycling

That number you see within the recycling symbol on recyclable plastic is called the “resin identification code” or RIC.  One pet peeve: the recycling symbol and RIC are often too small, not easy to see, or are difficult to find.  Also, some plastics and plastic parts that could be recycled are not labeled.

The seven different types of recyclable plastics are listed below, along with a small subset of initial and recycling uses.  New applications for recycled plastics are being invented all the time!  Perhaps you have some ideas.

Polymer: Polyethylene terephthalate (C10H8O4)n
Other names & abbreviations: PETE, PET, polyester
Common uses: beverage bottles, fibers for clothing
Recycling uses: non-food containers, strapping, carpet fiber

Polymer: High-density polyethylene (C2H4)n
Other names & abbreviations: HDPE, PE-HD
Common uses: milk jugs, food containers
Recycling uses: plastic lumber, parking bumpers, recycling bins, sheds

Polymer: Polyvinyl chloride (C2H3Cl)n
Other names & abbreviations: PVC, V
Common uses: bottles, non-food packaging
Recycling uses: pipes, fencing, flooring, lawn chairs, wire insulation

Polymer: Low-density polyethylene (C2H4)n
Other names & abbreviations: LDPE, PE-LD
Common uses: plastic bags, six-pack rings, containers, snap-on lids
Recycling uses: packaging foam, plastic film, garbage bags

Polymer: Polypropylene (C3H6)n
Other names & abbreviations: PP
Common uses: food containers, medical & lab equipment, pill bottles

Polymer: Other Plastics (acrylic, nylon, polycarbonate, etc.)
Other names & abbreviations: OTHER, O
Common uses: plastic lenses, food packaging & bottles, LCD screens, etc.
Recycling uses: plastic lumber, bus shelters, traffic lights, signs, etc.

Big Binoculars

It is often said (and rightfully so) that your first telescope should be a pair of binoculars.  And your second pair of binoculars should be big binoculars on a hands-free binocular mount.  It is amazing how much you can see (and how beautiful it is) at a dark-sky location with 16 x 70 binoculars mounted on an Orion Monster Parallelogram Binocular Mount & Tripod, for example.

And then there’s the realm of binocular telescopes, such as a 6, 10, or 16″ Reverse Binocular Telescope from JMI.  As famed astrophotographer Tony Hallas says in a letter in the July 2007 issue of Sky & Telescope, “Daphne and I have observed…many…deep-sky objects many times over the years using conventional telescopes, including very big ones.  Neither of us ever wants to go back to monocular observing.  Looking with both eyes through twin scopes with fast optical systems enables the brain to absorb so much more information—it’s utterly breathtaking.”

Vacuum Telescopes

The light from a celestial object is bounced and distorted as it penetrates the Earth’s turbulent atmosphere, and this image degradation continues all the way into the telescope.  Currents of air within the telescope tube caused by parts of the tube or optics being at different temperatures can severely degrade a telescope image, particularly in a large telescope.

Nowhere is this more apparent than in a professional solar telescope.  Sunlight entering the telescope heats up the inside of the telescope and optical components, resulting in turbulent air currents that make the images less sharp than they could be.

To solve this problem, some solar telescopes contain a vacuum so there is no air to heat and therefore no image distortion within the telescope.  This requires, however, a rather thick piece of glass (of high optical quality, of course) at the front of the telescope in order to maintain the vacuum within the tube.  A good example of this kind of telescope is the Swedish 1-m Solar Telescope (SST) located on the island of La Palma in the Canary Islands.

A much thinner front lens can be used if the telescope tube is filled with helium rather than evacuated, and though the results are much better than an air-filled telescope tube, they are not quite as good as with a vacuum telescope.

I am not aware of any vacuum telescopes being used for nighttime observations.

Meteor Watcher’s Network

I’ve been a meteor watching enthusiast since at least the early 1980s.  I had the good fortune back then of getting to know Paul Martsching when we both lived in Ames, Iowa, and few people in the world have logged more hours in the name of meteor science than he.  We have been close friends ever since.

We’ve learned that here in the U.S. Midwest, for any given astronomical event you wish to observe, there is between a 2/3 and 3/4 chance that it will be clouded out—unless you are willing to travel.  Weather forecasting has gotten much better over the years, and nowadays you can vastly improve your chances of not missing that important astronomical event, such as the Perseid meteor shower in August or the Geminid meteor shower in December.

Paul and I have traveled from Ames, Iowa to Nebraska, South Dakota, North Dakota, Kansas, Missouri, and Illinois over the years to escape cloudy skies.  Just last year, we had to travel to north of Jamestown, North Dakota to see the Perseids, and this year it appears we will need to travel to southern Kansas, Oklahoma, or Arkansas to get a clear view of the Geminids.

Weather forecasts don’t begin to get really accurate until about 48 hours out, so we often have to decide at nearly the last minute where to travel.  Therein lies the problem.  Where can we find a safe observing spot to put down our lawn chairs where there are no terrestrial lights visible brighter than the brightest stars, and no objectionable skyglow from sources or cities over the horizon?  It is a tall challenge.

What we need to develop is a nationwide network of folks who know of good places to watch meteors.  This would include astronomy clubs, individual astronomy enthusiasts, managers of parks and other natural areas, rural land owners who would allow meteor watchers on their land, rural B&Bs, cabins, lodges, ranches, and so on.  Once you know where you need to go to get out from under the clouds, there would be someone you could call in that area of the country to make expeditious observing arrangements for that night or the following night.  And perhaps lodging as well, if available.

If you would like to work with me to build a meteor watcher’s network or have ideas to share, please post comments here or contact me directly.

Do Dark Matter and Dark Energy Exist?

Numerous searches for the particle or particles responsible for dark matter have so far come up empty.  What if dark matter doesn’t really exist?  Could there be alternative explanation for the phenomena attributed to dark matter?

In the November 10, 2017 issue of the Astrophysical Journal, Swiss astronomer André Maeder presents an intriguing hypothesis that non-baryonic dark matter need not exist, nor dark energy either.  In “Dynamical Effects of the Scale Invariance of the Empty Space: The Fall of Dark Matter?” he suggests that scale invariance of empty space (i.e. very low density) over time could be causing the phenomena we attribute to dark matter and dark energy.

What is scale invariance?  In the cosmological context, it means that empty space and its properties do not change following an expansion or contraction.  Scales of length, time, mass, energy, and so on are defined by the presence of matter.  In the presence of matter, space is not scale invariant.  But take the matter away, and empty space may have some non-intuitive properties.  The expanding universe may require adding a small acceleration term that opposes the force of gravity.  In the earlier denser universe, this acceleration term was tiny in comparison to the rate at which the expansion was slowing down, but in the later emptier universe, the acceleration term dominates.  Sound like dark energy, doesn’t it?  But maybe it is an inherent property of empty space itself.

The existence of dark matter is primarily suggested by two  observed dynamical anomalies:

  1. Flat outer rotation curve of spiral galaxies (including the Milky Way)
  2. Motions of galaxies within galaxy clusters

Many spiral galaxies have a well-known property that  beyond a certain distance from their centers, their rotation rate (the orbital velocity of stars at that distance) stays nearly constant rather than decreasing as one would expect from Keplerian motion / Newtonian dynamics (think planets orbiting the Sun in our own solar system— the farther the planet is from the Sun, the slower it orbits).  Only there seems to be evidence that the rotation curves of galaxies when they are young (as seen in the high-redshift universe) do have a Keplerian gradient, but in the present-day universe the rotation curve is flat.  So, it appears, flat rotation curves could be an age effect.  In other words, in the outer regions of spiral galaxies, stars may be orbiting at the same velocity as they did in the past when they were closer to the galactic center.  Maeder writes:

…the relatively flat rotation curves of spiral galaxies is an age effect from the mechanical laws, which account for the scale invariant properties of the empty space at large scales.  These laws predict that the circular velocities remain the same, while a very low expansion rate not far from the Hubble rate progressively extends the outer layers, increasing the radius of the Galaxy and decreasing its surface density like 1/t.

We need to study the rotation curves (as a function of galactocentric radius all the way out to the outermost reaches of the galaxy) of many more galaxies at different redshifts (and thus ages) to help us test the validity of the scale invariant vs. dark matter hypotheses.  Maeder suggests a thorough rotation study of two massive and fast-rotating galaxies, UGC 2953 (a.k.a. IC 356; 50-68 Mly) and UGC 2487 (a.k.a. NGC 1167; 219-225 Mly), would be quite interesting.

The observed motions of galaxies within many galaxy clusters seems to indicate there is a substantial amount of unseen mass within these clusters, through application of the virial theorem.  However, the motions within some galaxy clusters such as Coma (336 Mly) and Abell 2029 (1.1 Gly) may be explainable without the need to resort to “exotic” dark matter.

Then there’s the AVR (Age-Velocity Dispersion Relation) problem which, incidentally, has nothing to do with dark matter.  But it may offer evidence for the scale invariant hypothesis.  It is convenient to specify the motion of a star in a spiral galaxy such as the Milky Way in a galactocentric coordinate system.

U = component of velocity towards the galaxy center

V = component of velocity in the direction of galactic rotation

W = component of velocity orthogonal to the galactic plane

Maeder writes:

The AVR problem is that of explaining why the velocity dispersion, in particular for the W-component, considerably increases with the age of the stars considered … Continuous processes, such as spiral waves, collisions with giant molecular clouds, etc… are active in the disk plane and may effectively influence the stellar velocity distributions.  However…vertical heating (the increase of the dispersion σW) is unexpected, since the stars spend most of their lifetime out of the galactic plane.

There may be more to “empty” space than meets the eye…

Theory and Observation

We continue our series of excerpts (and discussion) from the outstanding survey paper by George F. R. Ellis, Issues in the Philosophy of Cosmology.

Thesis F1: Philosophical choices necessarily underly cosmological theory.
Some cosmologists tend to ignore the philosophical choices underlying their theories; but simplistic or unexamined philosophical standpoints are still philosophical standpoints!

Cosmology, and indeed all human inquiry, is based on (at least) two unproven (though certainly reasonable) assumptions:

  1. The Universe exists.
  2. The human mind is at least to some degree capable of perceiving and understanding the Universe.

Any cosmological theory will have additional foundational unproven assumptions.  These are called axioms.  Ellis admonishes us to at least be aware of them, and to admit to them.

8.1 Criteria for theories
As regards criteria for a good scientific theory, typical would be the following four areas of assessment: (1) Satisfactory structure: (a) internal consistency, (b) simplicity (Ockham’s razor), and (c) aesthetic appeal (‘beauty’ or ‘elegance’); (2) Intrinsic explanatory power: (a) logical tightness, (b) scope of the theory—the ability to unify otherwise separate phenomena, and (c) probability of the theory or model with respect to some well-defined measure; (3) Extrinsic explanatory power, or relatedness: (a) connectedness to the rest of science, (b) extendability—providing a basis for further development; (4) Observational and experimental support, in terms of (a) testability: the ability to make quantitative as well as qualitative predications that can be tested; and (b) confirmation: the extent to which the theory is supported by such tests as have been made.

As you can see, a theory is not an opinion.  It must be well-supported by facts.  It must be internally consistent.  It must have explanatory power.  The Russian physicist A. I. Kitaĭgorodskiĭ (1914-1985) put it succinctly: “A first-rate theory predicts; a second-rate theory forbids, and a
third-rate theory explains after the event.”  Einstein’s special and general relativity are spectacular examples of first-rate theories.  In over 100 years of increasingly rigorous and sophisticated experiments and observations, relativity has never been proven to be incorrect.

Ellis emphasizes the importance of observational and experimental support in any scientific theory.

It is particularly the latter that characterizes a scientific theory, in contrast to other types of theories claiming to explain features of the universe and why things happen as they do.  It should be noted that these criteria are philosophical in nature in that they themselves cannot be proven to be correct by any experiment.  Rather their choice is based on past experience combined with philosophical reflection.  One could attempt to formulate criteria for good criteria for scientific theories, but of course these too would need to be philosophically justified.  The enterprise will end in infinite regress unless it is ended at some stage by a simple acceptance of a specific set of criteria.

So, even our criteria about what makes a good scientific theory rest upon axioms that cannot be proven.  But unlike religion, scientific theories never posit the existence of any supernatural entity.

Thesis F3: Conflicts will inevitably arise in applying criteria for satisfactory cosmological theories.
The thrust of much recent development has been away from observational tests toward strongly theoretically based proposals, indeed sometimes almost discounting observational tests.  At present this is being corrected by a healthy move to detailed observational analysis of the consequences of the proposed theories, marking a maturity of the subject.  However because of all the limitations in terms of observations and testing, in the cosmological context we still have to rely heavily on other criteria, and some criteria that are important in most of science may not really make sense.

String theory? Cosmic inflation?  Multiverse? If a theory is currently neither testable nor directly supported by observations, is it science, or something else?

Symphonies by Women

Last Updated: March 31, 2024

How many women have achieved the compositional milestone of writing a symphony for full orchestra?  The answer is, quite a few!  What follows is what I believe to be a comprehensive list of all symphonies written by women.  If you know of others—or if you find anything here that needs correcting or adding to—please post a comment.  So many of these works have been unjustly neglected.  The day will come (hopefully soon) when any short list of the greatest composers will include women.

When I originally started this list back in 2017, I had in mind only including works explicitly with titles such as Symphony No. 1, Symphony No. 2, and so on. But I’ve since learned that what constitutes a “symphony” defies any rigid definition, particularly when considering 20th- and 21st-century works. So, I’ve capitulated to include anything named “symphony” or “sinfonia” by the composer. Still, if you find any works here that really shouldn’t be included here as symphonies, please post a comment and I will consider removing them.

Looking towards the future, one composer to watch will certainly be Alma Deutscher.  Her first of what will hopefully be many symphonies is eagerly anticipated.

I’ve created a forum where you can post and listen to any available performances or recordings of works listed here (and in general) that are not yet (or currently) commercially available.  I hope you will consider participating, and please do tell others about it. Composers are welcome to post their own work, too!
