September 13 – Babcock

Horace Welcome Babcock (fantastic name), astronomer and inventor, was born today in 1912, son of solar specialist Harold D Babcock.  Babcock junior was the chap who realised that changing the shape of mirrors can be used to reduce the distorting effect of turbulence in the Earth’s atmosphere on light from distant objects (called adaptive optics). Unfortunately he made this discovery in the 1950s, roughly 40 years before the technology to actually do it became available.

Asteroid 12 Victoria, named after the Roman goddess of Victory (and possibly the queen of the same name) was spotted by John Russell Hind on September 13th 1850.  It’s an S-type, which you will recall are the stony asteroids, the second most common group, most of whom are congregated in the inner main belt.  Victoria has an apparent magnitude varying between 8.7 and 12.8, suggesting she is either elongated or binary.

Victoria the goddess was very important to the Romans (much more than her predecessor Nike had been to the Greeks).  I’m guessing this had something to do with her rôle in deciding who would be victorious in battle.

Asteroid 104 Klymene is a Themistian asteroid, discovered by J C Watson on September 13th 1868. The Themistians are a family of C-type asteroids, named after 24 Themis (and including 62 Erato, coming up tomorrow).

Klymene and Hera

Klymene and Hera

The name Klymene (or Clymene) crops up quite a few times in Greek mythology, but one of them, an attendant to Hera, stands out in my mind as being the most likely candidate for today’s rock, when you consider that the asteroid named immediately before this one was 103 Hera. This particular Klymene was an Oceanid (daughter of Oceanus) and you can see her, with Hera, in today’s picture, a detail of a depiction of the Judgement of Paris from the Badisches Landesmuseum, Karlsruhle.
