I love the sessions where the GRS is actually kinda obvious. Maybe in part because it's clarity is tied to the kind of observer planetary drawing has made me. I got up at 3 the following morning cause Io was not only casting a shadow but the moon itself was against a darker band, I was hoping I could pick it out. Saw the shadow, sadly not the moon.

Oh man was Jupiter great last night. I've seen as much detail on occasions but never more. There was a clear shadow being cast, I looked it up, it was from Europa. When I was all done I took one last look before breaking everything down and saw that the one moon not previously visible was emerging from behind the planet. I thought I was seeing the shadow of one moon and another coming around from behind. Turns out though that it was Europa in front of Jupiter, so though I was seeing great planetary detail I did not notice a tiny white ball in there. I almost decided to draw it again really fast - it be cool to capture the planet, a moon looking like an emerging pimple and a shadow ... but the cold was getting to me!!
