Jupiter, GRS and NEB Upheaval Animation

Captured on the 23rd June (local time), this animation represents 3 hours of rotation on Jupiter, as the Great Red Spot (quite a bit paler this year) transits across the face of the gas giant. Also visible, down lower on the NEB, is the new “NEB Upheaval” – a series of new spots and disturbances that are likely to change the look of the NEB for the remainder of the season.

Click the image to see the full 17-frame animation which covers 3 hours of rotation. It’s a 2.4mb gif file and will open in a new window.

The Galilean Moon, Io, pops out from behind Jupiter in the last frame of the animation. The red colour is because it hadn’t yet made much of an appearance in the blue and green channels (which were captured before the red channel). Io really moves fast!

Below is one of the 17 frames of the animation as a still image, from near the middle of the session.

This image below is frame #3 from the animation, taken at 1:35am local time. I used my 12″ Newt on the EQ6, with a 5x powermate and DMK21AU04.

All data was captured at 30fps, 1/30s exposure with gain at maximum and gamma at default.

Approx 700 frames from each channel was stacked to make up each image. The frames were all assembled in photoshop as layers, and exported as TIF files where they were then imported into Jasc Animation Shop 3 for creation of the animated gif.

It was a VERY dewey night – at times it was so heavy, it literally sounded like rain falling from the trees – but there wasn’t a cloud in the sky!

Below is the 14th frame from the animation. As you can see from the animation, the seeing was very variable and fluctuated between about 4/10 and 7/10 over the 3 hours. Unfortunately it didn’t scale the dizzy heights of “great” seeing, but it sure was nice to have some decent conditions after such a run of poor weather and poor seeing.

After capturing this 3 hours of Jupiter, I went back to bed to (try and) sleep for an hour, before getting up to capture my first Mars of 2009, and Venus in UV false colour. It sure was a busy and productive morning.

Thanks for looking.
