Problem Reports
PR NumberTimesTime LostDescriptionResponse
409403:47-03:4700:00SAMS was totally unusable with 20K+ TRSE and screaming -384 for all of mirror 13 sensorsCalled: Amanda T.

She had me use .cur from the morning before and remove the active sensors on mirror 13 (8:2) and presto, SAMS was happy!
409304:40-04:4000:00Unable to get CCAS DMI readings either through MARS or HEFI. See full text of pr for all the cool details.Called: Randy B., Mike W.

Somehow the second restarting of the DMI program appeared to work...
406407:52-07:52, 10:25 - 10:2500:00TCS became extremely slow.Exitted/restarted TCS
408408:04-08:0400:00Even though was fresh from a restart of TCS, every attempt to do anything in TCS resulted in an AsyncCommandSender error...Exitted and restarted TCS again and then all was well. For awhile.
407409:43-09:4300:00Tracker aborted trajectory while still far from end of track. I was not doing anything like focus changes or anything. The brakes fired and that was that. x = -1271.106 y = -1398.305 z = 132.732 AZ = 31.0921
409510:04-10:0400:00Heard clearly over the dome microphone something crashed, clanged, bounced from somewhere up above down to somewhere below. I was at the time slow slewing to lower right from position given in PR just above. Had already moved dome/structure to CCAS. Inspection shows a C-clamp just below Senior's boom that I am pretty sure was not there at OPS.Called: Herman

Herman is up in Senior atm.


Ops Commentsnone


TO CommentsInitially did engineering during twilight at West. Ron and Herman worked on dSpace down in LER first part of night. We tried to find satellites; failed. Used bright stars and rich fields in effort to get Hanshin's camera(s) to see light. 10:04 UT The thing fell from above, ending the night.


RA CommentsHanshin Lee here to work with deployable WFS in IHMP.
