6376	12:41-12:45, 20:36-20:36, 23:51-23:51	00:04	1] HPF stuck exposing during morning Part A calibrations, obsnum 073. This happened again during evening calibrations Part C, obsnum 097. Restarted detector client each time. 2] Timlimit exceeded for science target 178 with obsnum 54. I restarted the detector client and restarted the exposure.

TO Comments	Clear but 10 deg temp drop over course of night causing bad seeing.
