I took this short clip last Thursday morning just before sunrise while finishing off an all night starlapse. At first I thought the object was a comet near Jupiter, but after taking a shot I realized it was moving...although very slowly for a normal satellite.
I only got 44 frames before sunrise started to blow things out. Shot details:
10 sec exposure
12 second intervals (2 sec gap)
After processing and analyzing the sequence, I realized I'd captured a spinning de-gassing object, probably the spent stage of a rocket sending a satellite to Geosync or extra Earth orbit. The spinning is most obvious in the final 2 scenes, where I tracked the object using After Effects and zoomed to 100%. Things get a little noisy at that level.
Unfortunately, Vimeo compression has nobbled detail in the spiralling material apparent in the last 2 scenes (not to mention pixellating the ending). Download the vid if you'd like to see more detail.
