Pointing stable throughout most of the night. (~1 arcminute drift max over a long script)
Light clouds in the south on RASICAM for most of the night. Data taken was in the north and remained photometric.
Some guider problems though they can mostly be attributed to "luck of the draw" finding of u band stars bright enough for the guider. Target fields are at high galactic latitude and do not have many stars.
