Jupiter & Io 20220731
Jupiter on the morning of 2022 July31st… a night that was supposed to be clear but in reality had average seeing and poor transparency and more and more high cloud rolling in.
A quick look at Stellarium showed only 3 moons, as did the ephemeris feature of firecapture. Io I thought was in behind Jupiter and would come out around 04:30EDT, so I kept an eye out for it. As it turns out, it did come out on time. After processing, a surprise… it had been passing in front of Jupiter!
No Great Red Spot this session but Io more than makes up for it!
That is the bright spot in the lower right side of Jupiter.
This imaging session ran for about 2 hours, and ended up with 32 usable imaging runs.
Those were put together using the ImageMagick command: convert *.png jupiter.mpg
