An fk5 star was used to find the field in bright twilight. Seeing was about 1.0" as reported by the DIMM. Dust = 1.5K Seeing deteriorated; guider's estimation was about 2.5" We completed two exposures; both were < 2.0 S/N^2. 02:35 51815 10.0 flat 02:37 51816 2.0 arc 02:53 twilight ended 03:08 51817 1502.0 target 03:36 51818 1502.0 target 03:51Z Cart 06, plate 2895 (segue179). An fk5 star was used to find the field. This plate was declared done after two exposures; however, we later discovered that the lights were left on in the plug_lab, and the window shades were up.
