Problem Reports
PR NumberTimesTime LostDescriptionResponse
413507:30-07:3000:00Unexplained master fault while slewing to GOES 14. Had to abort and restart the trajectory which worked.
417211:30-11:3000:00Throughout the night the stars in the ACQ camera window had much larger tails then in previous nights. Some stretching the whole vertical column of the image. The effect seemed to lessen when the ACQ camera mirror was retracted and redeployed. Some of these images should be saved in the RA's data set.
418209:06-09:1000:04ACQ camera displaying interesting looking stars... Perhaps similar to the birdy error I have heard of but much smaller compared to images I have seen. Restarted the servers and the tcs gui now all is normal. See attachment in bug report.
413509:44-10:0700:23HFC fault while moving in x right after moving in y during a DWFS test. No error code given. Reset the fault and tried to reacquire the satellite with no luck. Restarted TCS and tried again with success this time.
417300:48-00:48, 06:15-06:15, 07:04-07:0400:00The -384 errors started again tonight but temperatures in the LER and UER were 70.70F and 64.22F respectively. This time it appears to be group B and only a few segments(See error list below). This may be different than what was experienced before. Dome conditions were as follows internal temp:14.3, Truss:15.2 Seg 89:15.4 DewPt Int: 9.1. Also checked that only one instance of SAMSServer was running on the SAMS computer.

TO CommentsThe beginning of the night was very humid and we were not able to open till significantly later. While stacking the humidity shot up again and we needed to close. We were finally able to observe after 2 am. AC seemed to be working almost too well....
