Problems: 
Several interlock problems tonight with files lost after long u, g exposures (720s,300s), these were fixed with Restart in the Observer Console. At 0448 UT queue stalled with no error messages. Finally able to start again after 15 min by pressing YELLOW stop under exposure bar in observer console, no file was lost. 0520 UT PanG went into a loop again but we were able to configure PanG component in the architecture window and then configure in observer console to restart (151044). At 0513UT noticed that guiding was not good due to oscillations that could be seen in the guide star strip chart. We were farther west than meridian but in the north at about -4.75 dec. Images looked bad with ellipticities in excess of 0.13 and extending E-W in a line of 0d (150149). Images were much better when we went to a more southern field (03.5h, -53d).
Comments:
