Classical Music Timeline: 1940s

This is one of a series of postings of important classical music dates, from the 17th century to the present. Included are the date and location of the birth and death of composers, and the premiere date and location of the first public performance of works. When the premiere date and location is unknown, the date or year of completion of the work is given. Though reasonably comprehensive, this is a subjective list, so the choice of composers and works is mine. If you find any errors, or if you can offer a premiere date and location for a work where only the completion date or year is listed, please post a comment here.

Solar Siblings

When our Sun formed 4.6 billion years ago, it almost certainly was a member of an open star cluster. Over several hundred million years, most of the stars in this cluster would have dissipated. Is there any hope, then, of finding some of our solar siblings?

I ran a query against the Gaia DR3 database to find stars with radial velocities and proper motions that are zero, within the measurement uncertainties. In other words, their space motions appear to be similar to that of the Sun. Could some of these stars be our long lost solar siblings?

First, some caveats.

  • 4.6 billion years is a lot of time, and dynamical evolution may lead to solar siblings no longer having comparable space motions to the Sun.
  • Error bars for the radial velocities, proper motions, and distances of many of these stars are large enough that subsequent more precise measurements may show that they are not co-moving with the Sun.
  • Though radial velocities are not affected by increasing star distance, proper motions are; therefore, proper motion in right ascension and declination will approach zero with increasing stellar distance
  • Some co-moving stars will be coincidental, especially if they are at large distances

I found 230 candidate stars in Gaia DR3 that appear to be co-moving with the Sun. They are listed in the table below.

Gaia DR3 SOURCE_ID Other Catalog RA (2016) Dec (2016) G Mag Distance (ly)

Please note that a distance of 999,999 ly (light years) indicates a Gaia parallax that is negative, meaning that the star is so far away that a reliable parallax cannot be measured. In other words, it is zero. Also, the farther away the star is, the more uncertainty there is in the distance.

19 of these 230 stars are bright enough, important enough, or lucky enough to have entries in the SIMBAD database. The nearest of these is TYC 8312-3134-1 which is 518 ly away in the constellation Norma.

We can do a simple BOTEC to determine how fast TYC 8312-3134-1 would have to be moving relative to the Sun to travel 518 ly in 4.6 Gyr. The answer is just 0.03 km/s = 30 meters/second. This is much less than the typical space motion of stars in the solar neighborhood relative to the Sun, which is on the order of many kilometers per second. It is therefore completely plausible that solar siblings could now be at a distance of at least 500 ly and even many times further than that.

Voyage to the Bottom of the Sea

When I was boy, age 8-11, I remember being enthralled by a television show called Voyage to the Bottom of the Sea. I even remember playing with a classic Bic pen, pretending it was the submarine Seaview.

Now, 60 years later, I decided to watch the whole series again. Despite all its flaws (some of which I list below), some of the episodes are pretty good.

What are the flaws? First and foremost, it is clear that Irwin Allen—the show’s creator—and many of his writers did not have a good understanding of basic science. Once you get past that, and the Seaviewpopping wheelies“, the Seaview “rock-and-roll” incidents (camera is rocked as the cast rushes from side to side on the set, simulating the submarine being tossed around), the frequent on-board pyrotechnic fires, a circuitry room that begs for a more secure door and an armed guard, and the all-too-frequent “monster of the week” and “mind control” episodes, you’ll always find an excellent cast of regulars (led by Richard Basehart and David Hedison), talented guest stars, and some imaginative stories.

So here goes…

Before you watch the television series episodes, I recommend you watch two submarine-themed movies.

The Enemy Below (1957)
This is a great movie, and includes David Hedison (credited as Al Hedison as Lt. Ware of the USS Haynes) who would go on to play Captain Lee Crane in the Voyage to the Bottom of the Sea television series.

Voyage to the Bottom of the Sea (1961)
This is the Irwin Allen film that later launched the television series. Once you get past the scientific inaccuracies (the Van Allen Belts on fire??), there is an excellent cast featuring such luminaries as Walter Pidgeon, Joan Fontaine, the ever beautiful and alluring Barbara Eden (before I Dream of Jeannie), Peter Lorre, Robert Sterling, Michael Ansara (before his role as the Klingon Kang in Star Trek and who was married to Barbara Eden at the time!), Frankie Avalon, and Del Monroe as Seaman Kowski who would go on the play Seaman Kowalski in the television series.

Voyage to the Bottom of the Sea (1964-1968)
The television series ran for four seasons. Here are my picks for the best episodes.

Season 1 (1964-1965)

Season 1, Episode 2: “The City Beneath the Sea”

Season 1, Episode 3: “The Fear-Makers”

Season 1, Episode 6: “The Sky Is Falling”

Season 1, Episode 7: “Turn Back the Clock”

Season 1, Episode 9: “Hot Line”
Directed by John Brahm of Twilight Zone fame, and guests include James Doohan and Michael Ansara before Star Trek.

Season 1, Episode 10: “Submarine Sunk Here”

Season 1, Episode 11: “The Magnus Beam”
Guests include Malachi Throne before his appearance on Star Trek.

Season 1, Episode 15: “Long Live the King”

Season 1, Episode 16: “Hail to the Chief”

Season 1, Episode 17: “The Last Battle”

Season 1, Episode 18: “Mutiny”

Season 1, Episode 19: “Doomsday”

Season 1, Episode 20: “The Invaders”

Season 1, Episode 23: “The Human Computer”

Season 1, Episode 28: “The Creature”

Season 2 (1965-1966)

Season 2, Episode 3: “…And Five of Us Are Left”

Season 2, Episode 10: “The Silent Saboteurs”
Guests includes George Takei before Star Trek.

Season 2, Episode 15: “Killers of the Deep”
Guests includes Michael Ansara before Star Trek.

Season 2, Episode 17: “The Phantom Strikes”

Season 2, Episode 22: “The Death Ship”

Season 2, Episode 26: “The Return of the Phantom”

Season 3 (1966-1967)

Season 3, Episode 5: “The Terrible Toys”

Season 3, Episode 13: “The Lost Bomb”

Season 3, Episode 19: “The Mermaid”

Season 3, Episode 23: “Doomsday Island”

Season 4 (1967-1968)

Season 4, Episode 3: “Cave of the Dead”
Guest star Warren Stevens was also a guest on Star Trek later that year.

Season 4, Episode 5: “Sealed Orders”

Season 4, Episode 6: “Man of Many Faces”

Season 4, Episode 7: “Fatal Cargo”

Season 4, Episode 8: “Time Lock”

Season 4, Episode 9: “Rescue”

Season 4, Episode 24: “The Edge of Doom”

Season 4, Episode 26: “No Way Back”

Of the 110 episodes of Voyage to the Bottom of the Sea produced, I think that 33 of them (30%) are well worth watching. Season 1 was the only season filmed in black-and-white, and the only season that had 32 episodes instead of 26. It was also the best season, with 15 great episodes. The next best season was the fourth and final season with 8 great episodes, followed by Season 2 with 6 great episodes. Season 3 was the worst season with only 4 great episodes.

Enjoy!

The Coldest Place on Earth

The coldest temperature ever reliably recorded on the surface of the Earth occurred on July 21, 1983, when a temperature of -128.6° F was recorded at Vostok Station, Antarctica (φ = 78° 27′ 52″ S, λ = 106° 50′ 14″ E, elevation 11,444 ft.). Located at the center of the East Antarctic ice sheet, Vostok Station is prone to extremely cold temperatures given its high elevation and location far inland (~868 miles) from the moderating influence of the ocean. Other contributing factors to the low temperature are the extremely low humidity (water vapor retains heat near the surface) and the high albedo of the snow and ice which reflects much solar radiation back out into space.

Vostok Station is the most isolated of all the established research stations on the Antarctic continent. Only about 30 scientists and engineers reside at Vostok Station during the summer months, but during winter that number dwindles to about 15.

The monthly average temperature at Vostok is as follows: April -84.6°F, May -86.4°F, June -85.5°F, July -88.1°F, August -90.2°F, September -86.8°F, October -70.8°F, November -44.7°F, December -25.2°F, January -25.6°F, February -47.7°F, March -72.2°F. The warmest temperature ever recorded at Vostok was +6.8° F on January 5, 1974.

For the current temperature at several locations within Antarctica, including Vostok, see https://www.timeanddate.com/weather/antarctica [apologies for the display ads, but out of my control]. For a Vostok weather forecast, visit https://www.yr.no/en/forecast/daily-table/2-6620791/Antarctica/Vostok%20Station. Planning a trip soon?

Vostok is a desert, averaging just 0.9 inches of snowfall each year. Does any non-dormant indigenous life exist at Vostok Station? No. Except for the human presence there, on the surface it is lifeless. But, fortuitously, Vostok Station sits above a giant freshwater lake called, appropriately, Lake Vostok, 13,100 feet under the ice. Scientists believe that life exists there, but they want to be very, very careful not to biocontaminate the lake as they begin exploring it in earnest.

It is interesting for us to ponder the possibility that sub-surface life exists on Mars and some of the satellites in the outer solar system. Though far more difficult than Lake Vostok to explore, someday we will.

Incidentally, at higher elevations along the Eastern Antarctica Plateau (specifically, along the ridge between Dome Argus and Dome Fuji), satellite measurements between 2010 and 2013 indicate that even colder surface temperatures than at Vostok Station have been reached, perhaps even as low as -144°F. However, since these are not surface temperature measurements, the current Vostok Station record of -128.6° F still holds as the coldest temperature ever recorded on Earth. And with anthropogenic global warming, that record is not likely to be broken anytime soon.

Factino: Did you know that it takes a lot more energy to cool down humid air than to cool down dry air? Air conditioners cool much more efficiently in Arizona and New Mexico than they do in Florida and Louisiana. Moreover, evaporative coolers in desert areas can reduce energy use by 80% or more over refrigerative air conditioning, but they only work well in dry climates.

Land of the Long Twilights

The first (and only!) sunset1 this year at Amundsen–Scott South Pole Station in Antarctica occurs on March 22 at 0615 UTC (using “astronomer’s time” as time zone has no meaning so close to the South Pole).

The year’s first and only end of civil twilight (when the geometric center of the Sun lies 6° below the horizon) occurs on April 4 at 1153 UTC. That’s 13d05h38m after sunset.

The year’s first and only end of nautical twilight (when the geometric center of the Sun lies 12° below the horizon) occurs on April 21 at 0409 UTC. That’s 16d16h16m after the end of civil twilight.

The year’s first and only end of astronomical twilight (when the geometric center of the Sun lies 18° below the horizon) occurs on May 11 at 0521 UTC. That’s 20d01h12m after the end of nautical twilight, and 49d23h06m after sunset. That’s one heck of a long twilight!

Night lasts from May 11 at 0521 UTC until astronomical twilight begins on July 31 at 1916 UTC. A duration of 81d13h55m.

Nautical twilight begins on August 21 at 0024 UTC. That’s 20d05h08m after the beginning of astronomical twilight.

Civil twilight begins on September 6 at 2121 UTC. That’s 16d20h57m after the beginning of nautical twilight.

The first and only sunrise of the year occurs on September 20 at 0945 UTC. “Morning” twilight lasts a total of 50d14h29m.

The Sun remains above the horizon continuously until sunset on March 22, 2025 at 1100 UTC. Daylight “hours” last 183d01h15m.

Strange place!

1Sunrise and sunset. For computational purposes, sunrise or sunset is defined to occur when the geometric zenith distance of the center of the Sun is 90.8333 degrees. That is, the center of the Sun is geometrically 50 arcminutes below a horizontal plane. For an observer at sea level with a level, unobstructed horizon, under average atmospheric conditions, the upper limb of the Sun will then appear to be tangent to the horizon. The 50-arcminute geometric depression of the Sun’s center used for the computations is obtained by adding the average apparent radius of the Sun (16 arcminutes) to the average amount of atmospheric refraction at the horizon (34 arcminutes).

Prokofiev and Astronomy

I recently completed teaching a six-week course on the Ukraine-born Russian/Soviet composer Sergei Prokofiev (1891-1953), a course I am eager to reprise in the not-too-distant future. His story is by turns both fascinating and tragic, and he wrote a lot of great music—much of it seldom performed. I am amazed that no one has yet produced an English-language documentary on Prokofiev, nor even a biopic.

Since my primary interests are classical music and astronomy, I am naturally curious about significant classical composers who were also interested in astronomy. Prokofiev was one of those composers.

Prokofiev kept fascinating and extensive diaries between 1907 and 1933, a practice which sadly ceased as soon as he began seriously contemplating a return to the Soviet Union and the increasingly repressive regime of Joseph Stalin.

Here are Prokofiev’s astronomy-related entries from those diaries.

The song Prokofiev is referring to here is Two Poems for voice and piano, op. 9, no. 1. The text is a poem by Russian poet Konstantin Balmont (1867-1942). Here is that poem in an English translation:

In this first performance, Anna Grigorievna Zherebtsova-Andreyeva was the singer, and Dulov (first name unknown) was the pianist.

Here is a performance of this work by Andrey Slavny (baritone) and Yuri Serov (piano), recorded at St. Catherine Lutheran Church in St. Petersburg in 1995.

The astronomy book Prokofiev was referring to is The World of the Heavens [Nebesny Mir], An Illustrated Astronomy for the General Reader by E. I. Ignatiev, published in St. Petersburg in 1916. Hardly a “little book” at over 400 pages!

When Prokofiev writes “the green and white diamond of Sirius” he must be referring to the impressive scintillation of Sirius, the brightest star in the night sky, since at the latitude (50° N) of Kharkiv, Ukraine, where he was at the time, Sirius never reaches an altitude higher than 23° above the horizon.

What’s an arshin, you might be wondering? An arshin is an antiquated Russian unit of length equal to 71.12 cm, so “two arshins” would be a little less than 5 ft. in length.

An editorial footnote indicates that “Presumably, Prokofiev’s Fraunhofer was looted or destroyed in the Petrograd flat after his departure in 1918. It would be worth a fortune today.”

Prokofiev continues,

Prokofiev again continues,

An editorial footnote indicates that “The White Nights in St. Petersburg are normally regarded as lasting from 11 June to 2 July. During this period the sun does not descend far enough below the horizon for the sky to become dark.”

Now on holiday on the Kama river, a tributary of the Volga, Prokofiev writes,

Prokofiev would only have been able to see four satellites of Jupiter with his telescope: Io, Europa, Ganymede, and Callisto. The other two “satellites” must have been background stars. If I have figured correctly, Prokofiev would have been observing Jupiter early morning on Friday, August 24, 1917 (New Style date) which would have been Friday, August 11 (Old Style date) in Russia at that time. The two stars he thought were satellites of Jupiter were probably 8th-magnitude stars HD 28990 and HD 28966.

Prokofiev’s reference to the Sun “belonging” to Hercules indicates he knew about the solar apex, the direction the Sun travels relative to the local standard of rest. William Herschel was the first to demonstrate that the solar apex is in the constellation Hercules.

Balmont refers to the aforementioned poet, Konstantin Balmont.

Prokofiev is referring to the 1917 Russian Constituent Assembly election during the Russian Revolution, and that he observed Venus, Jupiter, Sirius, and the Moon at Kislovodsk.

On his way to his first visit to the United States, Prokofiev is spending some time in Japan. At this time he is in Yokohama. At latitude 35° N, he is indeed getting a good view of Scorpius. The date in brackets is the New Style (Gregorian calendar) date, whereas the non-bracket date is the Old Style (Julian calendar) date.

Prokofiev is now sailing from Yokohama to San Francisco, by way of Honolulu.

Prokofiev is now in New York City.

Prokofiev is, of course, referring to the Royal Observatory, Greenwich, London, England.

This takes place in Paris, and B. N. is Boris Nikolayevich Bashkirov, a wealthy amateur poet and friend of Prokofiev whose pseudonym was Boris Verin. “Linette” is Lina Codina, who would become Prokofiev’s wife in two years’ time.

An editorial footnote states, “When staying in Les Rochelets in the summer of 1921 Prokofiev every evening read aloud a chapter of H. G. Wells’s The Outline of History to his mother and Boris Bashkirov.”

Interesting that this insightful essay was penned on “Pi Day”, since the transcendental π = 3.1415926535897932384626433832795… has infinitely many digits that neither terminate nor enter a permanently repeating pattern.

My take after reading this is that there may be two realities. One reality (our reality) consist of entities that exist within time and space. But there is another reality, where there are entities that exist outside of time and space (of which eternity and infinity are proxies).

As for immortality, since I have no consciousness of anything before I was born, why should I expect that I would have any consciousness of anything after I die? To me, that is the most tragic fact of human existence. Within a few minutes (or hours, if extraordinary measures are taken) after death occurs, all of our knowledge and experience—our memories—are irretrievably lost, and all that remains of us is what we have left behind (writing, music, art, etc.), and the memories of those who are still living who knew us. After all the people who knew us personally have died, then all that remains of our existence are artifacts. And, eventually, all of those will be gone, too. This truly emphasizes the importance of this life, of this world, of this time. How we live our lives and treat others today, tomorrow, and the next day are of paramount importance. It is all we have, or will ever have.

Fatou refers to Pierre Joseph Louis Fatou (1878-1929), mathematician and astronomer. I am virtually certain that “Jacobi” is actually the French astronomer Michel Giacobini (1873–1938).

Here are my observing notes about Gamma Leonis:

Algieba.  Very bright, close double.  Primary is orangish-yellow (2.6 K1-IIIbCN-0.5) and secondary is yellow (3.8 G7IIICN-1).  Relative color seems to change as you watch. 

I think it only fitting to end these excerpts from Prokofiev’s diaries with some of his music. In preparing my Prokofiev course, I came across some noteworthy compositions that were not known to me previously. Most unfortunately, some of these works are almost unknown and seldom played because they were written (under duress, without a doubt) as propaganda pieces. Here is, I believe, his most inspired composition written under such circumstances. It is a cantata for chorus and orchestra that Prokofiev wrote in 1939, called Zdravitsa (literally “A Toast!”), op. 85. It was written to commemorate the 60th birthday of Joseph Stalin. The words are hagiolatry in praise of Stalin (Prokofiev did not write them), but the music is truly divine. Here are three excerpts from a recording by the Russian State Symphony Orchestra and the Russian State Symphonic Cappella, conducted by Valeri Polyansky.

The first excerpt is of the orchestra alone:

Now, choir and orchestra:

And, finally, the glorious finale:

I look forward to the time when Russia will be free from tyranny, and when this gorgeous piece by Sergei Prokofiev gets a new libretto. No longer a toast to the despot Stalin, but a toast to peace-loving people throughout the world!

TYC 5134-1820-1: A New Double Star Discovery

Shadow path of TYC 5134-01820-1 occulted by asteroid 1330 Spiridonia – June 26, 2023 UT

On 26 June 2023 UT, Vince Sempronio near Benson, Arizona and David Oesper near Tucson, Arizona observed an occultation of the 12.2-magnitude* star Tycho 5134-1820-1 in the constellation Aquila by the 15.1-magnitude asteroid 1330 Spiridonia. The predicted magnitude drop should have been around 2.9 magnitudes (15.1m-12.2m) by both observers, but I observed only about a 0.2-magnitude drop, and Vince a 1.5 magnitude-drop. After expert analysis by David Gault and David Herald in Australia, it was determined that we had discovered a new double star!

Observer locations for the June 26, 2023 occultation event

Fortuitously, Vince had observed 1330 Spiridonia covering up only the primary (brightest) component, and I had observed 1330 Spiridonia covering up only the secondary component. Both of us made our observations with 8-inch telescopes.

Vince Sempronio’s light curve (11.2 seconds, 70 data points)
David Oesper’s light curve (60.7 seconds, 455 data points)

The double star solution from our observations gives the following:

G magnitude of the primary component: 12.4

G magnitude of the secondary component: 13.9

Separation: 59.7 milliarcseconds (0.0597 arcseconds)

Position Angle: 141.8° (eastward from north)

The double star solution

Follow up observations over time will be needed to determine whether this is an optical double (chance alignment) or a true binary system. The distance to TYC 5134-1820-1 is currently estimated to be between 2,689 and 2,883 light years (SIMBAD). Definitely not in the neighborhood.

Even though double stars are common in our galaxy (and everywhere else in the universe), and understanding that our observations represent only the tiniest contribution to scientific knowledge, there is satisfaction in knowing that we discovered something not known by anyone else before. Besides, you never know when a discovery such as this will draw attention to an unusual and astrophysically-interesting system.

In conclusion, here is but one example showing that observations of stellar occultations by the minor planets of our solar system presents an exquisite method of discovering very close double (and possibly binary) stars, not assayable by any other technique.
