I know seeing is supposed to be below average, but ya (almost) never know.

Starts in twilight (I'd guess).

Io's shadow currently visible. Seeing is "okay" in Marin. I grabbed my TV85 and went out back. Shadow is discernible at 85x and pops at 133x. I do not see Io itself.

Red Spot is due to rotate into view soon. Enjoy!

Thanks for the heads-up, Mark. Seeing is not bad at all here in Mountain View. To my eye, the shadow seems smaller compared to Callisto’s one the other week.

Seeing in Los Gatos is awesome.  10" f/5.7 and image just begins to break down with 3.5mm Nagler.  Steady and clear with a 4.8.  Shadow sitting nicely in the white of the equatorial belt, above a thick rusty southern band, south edge very scallopy, one additional thin band southward still, and a pair of them thinly to the north above the northern (also rather thin) equatorial band.  Excellent view.

And, split the Pup with the 4.8 Nagler.   I'm happy.

If you split Sirius you’ve got great seeing.

And now the GRS is coming into view.
