Winds were high all night, but never gusted much above 30 mph, averaged around 20 mph.Sky was hazy with varying amounts of low, light clouds, never photometric.

Starting with image #58 (taken at UT 07:53), the upper right (NW) chip appeared to stop collecting photos. I’ve no idea why this happened (it was an unremarkable star otherwise), but I was able to manually shift all of my targets onto one of the three normally-functioning CCds .
