In the end I imaged for another 30 minutes only because the conditions were If it really was an impact mark then I had to start telling people, and quickly. Could it actually beĪn impact mark on Jupiter? I had no real idea, and the odds on that happening were so smallĪs to be laughable, but I was really struggling to see any other possibility given the location Now I was caught between a rock and a hard place - I wanted to keep imaging but also I wasĪware of the importance of alerting others to this possible new event. That exact region only 2 days earlier and checking back to that image showed no sign of It took another 15 minutes to really believe that I was seeing something new - I'd imaged Was at the cloud level and not a projected shadow from a moon. Oval storm that I was very familiar with - this could only mean that the back feature As far as I could see it was rotating in sync with a nearby white Also I'd noticed it was moving too slow toīe a moon or shadow. It was in the wrong place and the wrong size. My next thought was that it must be either a dark moon (like Callisto) or a moon shadow, but I suddenly realised that it wasn't just dark, it was black in all channels, However as it rotated further into view, and the conditions improved (and in poor conditions) it was only a vaguely dark spot, I thouht likely to be justĪ normal dark polar storm. Jupiters south polar region started to get curious. When I came back to the scope at about 12:40am I noticed a dark spot rotating into view in Indeed I had hovered the mouse over the exit button on my captureĪpplication (Coriander for Linux) and then changed my mind and decided instead to simply takeĪ break for 30 minutes and then check back to see if the conditions had improved. By about midnight (12:10 am) the seeing had deterioratedĪnd I was ready to quit. Recording data until maybe 1am local time.
I was pleasantly surprised to find reasonable imaging conditions and so I decided to continue The scope in use was my new 14.5" newtonian, in use now for a few weeks and so far returning The temperature was also unusually high for this time of year (winter), Weather prediction was not promising, clear skies but a strong jetstream overhead according I started this imaging session on Jupiter at approximately 11pm local time (1300UTC).
