There was a transit of Io with its shadow,I had to image while Jupiter was very low to catch this. Io is not visible but it's somewhere near the centre of the disc. There is an obvious dark spot near that position but I'm not sure if that's Io or a cloud spot.

Condition still not good. Jupiter is still very low in the sky only around 20 degrees above the horizon.
Oval BA is very pale in this image. The NEB is very dark red. The SEB seems tohave the same color but with a mid-SEB activity. There are some dark features north of the NTB.

On Sunday morning, I was able to capture my first Jupiter moon transit for
the season, with the volcanic moon Io transiting the gas giant. I also took
the opportunity to create my first Jupiter animation for the season,
hopefully the first of many to come.

It was another busy morning (like Friday morning) with an ISS pass, a lovely
crescent Moon and then of course Jupiter. Seeing was quite reasonable, and
improved as Jupiter climbed out of the muck, reaching an altitude of about
39° literally 5 minutes before sunrise when I captured my last image. The
sky was already blue and by this time I could only just see Jupiter naked
eye.

The attached image is the best from the session, taken 10 minutes before
sunrise and shows Io just about to leave the disc of Jupiter. Oval BA is
rising on the right.

I captured 8 frames to create an animation, and you can see the seeing
improves as Jupiter gets higher in the sky over the 1 hour of capture time.
The first frame shows Io’s shadow just leaving the disc.
