Sketching's Finalist - Asbytec
Here's my entry for Jan 2014 sketching contest.
I chose this one because it was the most unique so far this season. The Io transit shortly after opposition was amazing in that I suspected being able to observe Io eclipse it's own shadow. It was also faintly visible against the SEBn.
The festooning was pretty nice, but the cloud features in the north were quite nice even if LRS-1 was missed. Some of the rifting in the SEB was unique, as well, in that it's not often observed. Neither are the ovals in the SSTeB preceding the GRS. It was a great night worthy of sharing.
This sketch was made beginning 1700UT on 8 Jan from Luzon in the Philippines. Seeing was good to excellent, transparency was average. Equipment used was a 150mm MCT on an undriven EQ mount. Magnification was 240x with 8mm TMB II.
I'd prefer to submit the sketch in my avatar, it is more detailed and maybe a little better rendered. This one is more unique, so it was a tough choice. I hope I chose well. The write up is here.
Good Luck to all our finalists!

The uncanny sight of Io projected above Jupiter like that resting in its own shadow has a unique 3D effect that's quite captivating. How often its no where near its shadow and can be lost in the mix as it transits.

I could not see Io so much as just able to tell where it was. It's hard to convey that in a sketch, but I tried. At times, I thought it might peak into the EZ south. However, seeing where Io was and it's shadow were very close together. If the shadow were further out, I am sure Io would have been much more difficult to locate. The perceived elliptical behavior of the shadow actually aided in locating it, if that makes any sense. "Oh, yea, Io is right there. Right next to it's shadow. Cool! Is it overlapping this far past opposition? Man, hard to tell, but maybe it is."
Doing the math as to whether the eclipse of it's own shadow was possible turned out to be very close and inconclusive either way. It just might have covered a small edge of it's shadow. Maybe someone with better skill at ephemeris can say better whether it actually was or not.
In any case, it's an interpretation of what looked to be a very slight overlap and not an image proving it either way. I really think it was, though. That was the impression I was getting without knowing in advance, only knowing Jove was past opposition. It was a nice sight, regardless, and worthy of a sketch.
