Well the weather was temporarily clear so I figured "why not, it's my last chace for a week". Took the 10" Dob outside to cool.

After an hour and 30 of cooling with the fan on, I nudged the collimation into place as good as I can get it by shining my red light on the opening of the cheshire.

Telescope: 10" Newtonian
Seeing: 4/10

As I pointed the scope at Jupiter, it immediately became apparent that the seeing was absolutely no good. Well, I didn't expect much in the first place as that jetstream was over us again. Indeed, when I defocused the planet slightly, the shimmering was crazy! Imagine looking directly above a fire. Any low contrast and delicate feature would be washed right away in these conditions.

At 166x I made out 7 belts and the GRS was present this time. It featured a pale pink colour. I could detect some ruffling in the SEB and NEB in moments of good seeing. I caught a shadow transit of Io, and at 9:29 UT the moon itself emerged from a transit at the planet's eastern limb. The EQ band was very obvious, to the point where I could see it varying in thickness. Didn't see much festoon and white oval activity along the southern fringe of te NEB which I put down to either a quiet day on the planet or the poor seeing.

All in all, the view was pretty good considering the bad conditions. Can there possibly be a a night of good seeing before we lose Jupiter for this year?
