A Busy Day at Jupiter
The night of Wednesday October 20 was a busy one, Chez Reynella went to a meeting were we hear the first about the EPA report that would cause a storm in the media and parliament.
Then when we got home there was a multi-satellite event on Jupiter. With Io passing behind Jupiter, Europa doing a shadow transit of Jupiter and Ganymede coming out from behind Jupiter's shadow.
In the video you can see all of this happening. I took images at 10 minute intervals so I have a sequence of 16 images. Unfortunately, it was a warm night. Why do I say unfortunately? Because the seeing was terrible with atmospheric turbulence bouncing the image all over the place. Even at midnight it was still wobbly.
Each individual frame was derived from a 20 second AVI taken with my Philips ToUCam webcam, which was subsequently stacked using Registax5 with mild wavelet adjustment. So I got some detail. The Moons are somewhat distorted, but you can clearly see the shadow of Europa and Ganymede popping out of eclipse is quite dramatic. You can download a 14 meg AVI or a 2 meg GIF animation for your viewing pleasure.
