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, Ganymede + Shadow, and Wesley Impact Scar
Last night started like every other – typically below average seeing, but instead of going back to bed, I waited it out – hoping it would get better. And it did! The seeing peaked at 7 – 7.5/10, on a night when there was a fair bit going on. The GRS transited earlier, followed by [...]
Ganymede Occulting Io – My First Galilean Moon Occultation!
UPDATE: See below for a new colour image of Io and Ganymede. This morning I was able to capture my first Galilean Moon occultation, when Ganymede passed in front of Io, covering about 40% of the volanic moon. The seeing was reasonably stable, maybe 6.5/10 and the morning started off beautiful and clear. Some cloud [...]
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 [...]
Jupiter and Ganymede – My Best This Year!
Seeing was great this morning, 12th May local time, the best I’ve had all year. Ganymede was approaching Jupiter, soon to begin transit. Here’s one of the 11 images I captured from this morning – the first one to be fully processed and one of the best from the session. The others are still at [...]
From the Vault: Jupiter and the Galilean Moons
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 a portrait of Jupiter and the Galilean Moons, the Jovian system [...]
From the Vault: Dynamic Jupiter in Motion
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 shows a Dynamic Jupiter in Motion with an image montage and [...]
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 [...]
A busy night on Jupiter
I’d been looking forward to this busy night on Jupiter for over a week and was lucky enough to wake to clear skies and above average seeing. Unfortunately though, I’d only captured 3 runs before blanket cloud put an early end to the session. Very disappointing, as I had a feeling the seeing would’ve improved [...]
