Jupiter Io transit animation - 17th Sept 2020

[lukebl]

This is a brief animation of Io and its shadow transit from last night, 17th September 2020, 19:55 to 20:25 GMT.

I captured 5000 frames at about 100 fps every 5 minutes. ASI290MM Mono Mini cam, 200mm f/5 Newtonian, 3x Televue Barlow, Baader IR filter.

As you'd expect, with it being only 14 degrees above the horizon, seeing was absolutely atrocious so there's not much detail. What you can see, though, is that there seems to be a lot of disturbance at the moment in North Equatorial Belt, with a large barge directly under the shadow and a circular feature appearing on the left (obvs. not the GRS as that's in the SEQ).

Here's a few of the pre-processed individual frames, to show you what I was up against!

Well that is a massive dark barge isn't it?! Jupiter is so interesting at the moment. Great stuff👍
