The seeing was quite poor again last night, but it began to steady as the skies thickened near the time of culmination for this image of Jupiter with Io and Io’s shadow transiting the disc.
Here’s Jupiter with Ganymede nearing the beginning of its transit and the Great Red Spot looking a bit lonely in a very bleak looking GRS hollow. This was taken in a steadier moment of generally poor seeing. The clouds ended the session before I could capture the transit.
And one through a near-IR filter. The GRS nearly disappears in the near-IR!
Some nights, it’s just fun to watch Jupiter on the computer monitor and hope for something interesting, because some night the seeing just isn’t very cooperative. Last night was one of those nights. Unfortunately, Jupiter didn’t do anything interesting. Neverthless, here’s a picture from near culmination (i.e., when Jupiter is as its highest point in […]
Imaging conditions were poor last night with low transparency, a strong jet stream, and quite a bit of wind. Nevertheless, I wanted to watch the double shadow transit from its moons Ganymede and Io. The conditions didn’t cooperate early enough in the session, but I managed the following image showing Jupiter with Ganymede’s shadow in […]
It’s been frigid here in the eastern U.S. over the past few months. Despite the cold (the temperature sensor at the focuser said 14F at the start of the session), the skies cleared long enough to get a few hours of imaging data for Jupiter, last night. The seeing was fair, despite a 100mph+ jet […]
