6464	01:05-01:05	00:00	Truss temperature sensor giving unreasonable values	Monitored other temperatures
6665	04:33-04:34	00:01	Night Report sometimes showing expXX_to.dir instead of filename
6666	06:52-07:05	00:13	Dome failed to reach target at approximately 180 degrees. Possibly due to the dome track ending on a previous target near 180, and then moving but not getting up to full speed before becoming stuck.	Stopped dome and reset dome inverters
6554	08:14-08:28	00:14	HPF ACQ images weren't updating	Restarted PAS and continued setup
