On the way home from town Saturday night I noticed the Moon was shining through thin high clouds, it was very still, and everyone's chimney smoke was flattening out instead of rising up into the air. This indicated a temperature inversion so I thought maybe the seeing might be decent.
As it turned out, the seeing was average but with long moments of steadier air. More of a problem was the transparency. The clouds got thicker and thicker until the only stars I could see were Aldebaran, Betelgeuse, Rigel, and Sirius. Through the eyepiece Jupiter's finer details became harder and harder to detect so I had to work fast on this sketch.
The ends of the two main belts seemed to wash out on the limbs, perhaps a function of opposition, so I wasn't able to get a very good look at the turbulence following the GRS. Surprisingly, Oval BA was quite easy to see (I timed it on the CM at ~155°) and appeared a beautiful salmon color. The little dark spot following popped in and out with the seeing.
Also, three distinct bright ovals were on the northern edge of the Equatorial Zone. I suspected they were outlined by faint festoon plumes but I couldn't confirm.
Only three Galilean moons were visible--Io was behind the King.
Glad I got this one done--last night's opposition was rained out here.
