Well this animation has been a long time coming. Back on the 5th July 2009, Ganymede and Callisto had a close approach – no occultation unfortunately, but it was still great to see them so close together. Ganymede, at 5,200km diameter (1.7 arcseconds) and Callisto at 4,800 km diameter (1.6 arcseconds) are both over 635 [...]

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 [...]
From the Vault: Jupiter and Callisto Transit Animation
In the From the Vault series, I feature an older image which hasn’t been seen here before and I talk about the capture and processing and hopefully highlight why this image is special to me. The feature image in From the Vault this week is an image and animation of Jupiter with Callisto in transit. Captured [...]
Jupiter + Ganymede Animation, 12th May 2009
On the morning of the 12th May, I had some very good seeing – the best I’ve had all year, and I was able to record some images of Jupiter and Ganymede in very good conditions, allowing surface details (albedo features) to be seen on Ganymede – one of the Galilean Moons of Jupiter, 750 [...]
Saturn with Rhea Shadow Transit
On Wednesday night I captured Saturn in above average seeing – the second time that week! When I’d finished processing the images, I noticed a faint Moon near the edge of Saturn, and a dark feature just under the ring plane. When blinking between the two images, I saw that the feature had moved, so [...]
Jupiter with Io and Shadow Transit Animation in Good Seeing
This morning, 7th May local time, I had reasonably good seeing for about an hour – long enough to capture 7 runs of Jupiter with the Galilean Moon Io and its shadow transiting across the Jovian disc. The red channel was pretty good in almost all images, but unfortunately the blue channel was pretty ordinary, [...]
Jupiter and Io Transit Animation, 21st March 2009
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 [...]
Jupiter, GRS and Ganymede Occultation
New images of Jupiter are always news-worthy, and this is no exception. I received an interesting link on the ALPO_Jupiter yahoo group the other day – it’s a pretty fascinating animation showing Ganymede being occulted by Jupiter. Here’s a still from the movie: Read on to see the animation and to see one of my own [...]
