88 Constellations, One Musical Instrument

Of all the constellations in our sky, only one is a musical instrument: Lyra the Lyre.  A lyre is a stringed harplike instrument used to accompany a singer or reader of poetry, especially in ancient Greece.  One wonders what strange and lonely enchantments await the contemplative listener as Lyra wheels through our zenith these short summer nights.

Nova Scuti 2018

Nova Scuti 2018 (or N Sct 2018, for short) was discovered by prolific nova finder Yukio Sakurai of Japan on June 29, 2018.  His discovery image at 13:50:36 UT showed the nova shining at magnitude 10.3 (unfiltered CCD magnitude), using only a 180-mm f/2.8 lens plus a Nikon D7100 digital camera.  One of his many discoveries is named after him: Sakurai’s Object.

What is a nova?  A classical nova is a close binary star system that includes a white dwarf and a “normal” star.  The white dwarf siphons material off the other star until a critical density and temperature is reached in the atmosphere of the white dwarf, and a thermonuclear detonation occurs.

Nova Scuti 2018 will eventually receive a variable star designation (V507 Sct?).  Here are some typical nova light curves.

Nova Scuti 2018 is located fortuitously close to the 4.7-magnitude star Gamma (γ) Scuti.

Here is a time sequence of images I’ve acquired of Nova Scuti 2018.  Comparing with the star chart above, can you find the nova?

Gorgeous Grieg

Norwegian composer Edvard Grieg (1843-1907) is best known for his iconic Piano Concerto in A minor, op. 16, written in 1868 when the composer was just 24 years old, and his Peer Gynt suites, No. 1, op. 46 (1875, 1888), and No. 2, op. 55 (1875, 1891).  Like Tchaikovsky, Grieg had a gift for melody.

Grieg once wrote, “Artists like Bach and Beethoven erected churches and temples on the heights.  I only wanted to build dwellings for men in which they might feel happy and at home.”  With this in mind, you will find no better introduction to some of the other gorgeous music that Grieg wrote than Norwegian conductor Bjarte Engeset conducting Sweden’s Malmö Symphony Orchestra on Naxos 8.572403.

Seldom have I found a disc of music so beautifully paced and played.  These five pieces for string orchestra (augmented by oboe and horn on “Evening in the Mountains”) followed by one piece for full orchestra provide the listener with over 71 minutes of pure enjoyment that will convince you (if you weren’t already convinced) that Grieg deserves a place alongside the most significant composers of the late 19th and early 20th centuries.  For me, personally, every one of these pieces is a favorite.  There is nothing to skip over here!

Don’t let words like “gorgeous” and “pure enjoyment” give you the impression that this music is lightweight fare.  There is a sadness in this beautiful music that evinces that it is anything but superficial.  Grieg and his wife Nina lost their only child, Alexandra, to meningitis when she was little more than a year old, Nina later miscarried a second child, and Grieg himself suffered all his adult life from the effects of pleurisy he had contracted when he was 17 years old.
