An interesting event was caught last night on the allsky1 camera system.
This is one still of 16. The interesting bit is the large cloud near the centre of the image.

It lasted from 18:25:28 EST – 18:40:22 EST or 15 minutes and appeared to be a large cloud or rocket fuel cloud moving south to north while the prevailing winds were moving all the other clouds from west to east (right to left).

It does look similar to spacecraft fuel dumps seen in the past. We are trying to track down a possible spacecraft that may have caused this.
