On Saturday night 8th August, I was able to capture some images of Jupiter with Io and its shadow in transit. The seeing was just above average – good enough to capture albedo features on Io, including the dark polar regions in contrast against the cloud tops of Jupiter. The best image from the session [...]

45 Cap, Europa and Io – Close Approach
Today (3rd/4th August) in parts of Europa, Africa, South America and the Middle East, Jupiter is due to occult the star 45 Cap – something that happens very, very rarely. For other parts of the world, including mine, the star wasn’t occulted by Jupiter but instead gathered close enough in the field of view for [...]
Busy Night (3 Events) at Jupiter Tonight! (27th July)
Tonight (27th July) is a very busy night on Jupiter with 3 events worth observing and imaging. All times in AEST. The Wesley Impact Scar will be visible between about 10pm and midnight. It transits the CM at about 10:40pm. Also tonight, at 11:24pm (lasting for about 8 minutes), Io’s shadow eclipses Europa. Then later, [...]
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 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 with Io Shadow Transit, 29th March 2009
On Sunday morning, we had beautiful clear skies and I was able to capture an image of Jupiter with Io’s shadow in transit, followed by Io itself shortly after. Unfortunately the conditions weren’t great and the image is really affected by the poor seeing, even though Jupiter is now climbing to a respectable 40-45° in [...]
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 [...]
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 [...]
