Friday 29th August 2014 Minor Planet 1994 YZ
I was checking one of my galaxy images - PGC 24464 - taken in the early hours of 4th January 2012 and noticed a trail near the galaxy. The exposure was only 30s so it would have to be a fast moving object - or possibly a cosmic ray - although cosmic rays tend to be thin wiggly streaks usually. I solved the plate in CCDSoft and The Sky indicated that there were in fact two minor planets in the field of view at that time and added green circles to my image to pinpoint them. Not surprisingly the 21st mag minor planet does not show but the Mag 18.6 one is in its circle as indicated. Any solutions to the mystery trail invited!
