Problem Reports
PR NumberTimesTime LostDescriptionResponse
415501:02-01:0400:02APC GUI error when trying to turn on the wavescope. See full text the extremely wordy error message.
415601:49-01:5700:08RA sent target to tcs and it not arrive, so exitted/restarted all tcs stuff.
415702:12-02:1400:02Streaks on guider, but definitely ties to the east/west thing for 180's.Easy to devise work around once I realized the prolmen
415803:19-03:3900:20trajectory hung in a new way for me. no maxing of top, see full text of pr for deets, I starting to lose track of prs again.Klicking abort move way more often and exitted/reastarted all tcs stuff, of course.
416303:54-03:5900:05TCS GUI crashed to desktop while trying to get TT loop going! It give no error, at least I didn't see one.First ever seen this; restarted just gui and it seemed fine...
415905:19-05:2900:10Failed to acquire trajectory error message and and on Control desk there is master fault and power column blinking on and off.Cleared fault and attempted to move on, into the next PR as it turns out.
416005:29-06:1700:48Was skewing to a star; there was a really odd noise I had never heard before, a following error code 24, and a real following error on Y and CFD load cell was 4800! Called: Jim Fowler

Much exitting/restarting tcs stuff and abort clicking but nothing was setting the slew brakes for UX, LX and Y. Recycled power dSpace.
416106:22-06:3000:08Streaks on guider and "failed to acquire trajectory" but without the faults on COntrol Desk or blinking on/offness as in prior pr sometime tonight, so make new prUsual exit/restart all tcs stuff.
416206:41-06:4600:05Weirder than most, brakes fired, my star vanished. TCS still had green light on trajectory. I click Abort, got an error msg, TCS was no longer reaching dSpace with commands. Error msg in full text pr.Exit/restart all tcs-ness
416407:29-07:49, 08:34 - 08:45, 10:09 - 10:12, 10:18 - 10:2300:39HFC fault while setting up on DIRECTV 10 just like 2-3 minutes after it started tracking.move off a bit in structure then try8ing trajectory agian. It move struct but never begin track. I exit/restart all tcs-ness
413908:46-08:5800:12Once again was trying to go to satellite, it moves the struct, it slews to start and fails to ever start tracking. Now, THIS time at the command line when it returned a prompt it barfed up an error msg !!Exit/restart all tcs stuff.

TO CommentsClear at sunset. 0.3 dust is as usual, in the red zone but not 2X. Stayed in red most of night but towards dawn, actually dropped into the green zone. Sorry about poor write-ups on PRS, they kept happening and I kept getting further and further behind and so forgetting and confusing details; about all I could do at the pr occurance was jot down the time. Triggered recording is on, but I haven't seen it actually record anything at all tonight, dunno why.
