↪ CommentsOne bad iteration in AOA. The Undo command did not fix it. Pretty much needed to start over.

Problem Reports
PR NumberTimesTime LostDescriptionResponse
437003:38-03:4200:04TCS server went defunct while going to a trajectory. No error displayed, only indication was the TCS led on the Tcs Gui.Shut down all servers and gui and restarted them.
169604:41-04:4100:00Took out Sensor 74-5 for LTRSE.
437105:11-05:11, 07:04-07:0400:00Camera feeds all went down, no signal on the TVs from any camera no matter the switch/multiplexer setting.Response: Matthew unplugged the power on the back of the multiplexer (video switch) and plugged it back in and they came back. I did the same the second time to fix it.
436905:39-05:3900:00Timestamp (date +%s command): 1454045759 While taking CWFS images readout taking a long time (~20 to 30 seconds).Tried to restart all the servers and the gui to see if that would help. It did not.
433010:11-10:1100:00Chirping very frequent tonight when wavescope was off.
436706:26-06:27, 08:52-08:5200:01HTCS time (date +%s): 1454048762 Got the "Failed to set processing parameters" error while trying to start loop on ACQ camera. After I hit ok and gave it a second, I hit start loop again and it worked. I was then able to guide as normal. See error and possible cause in PR.
433010:29-10:2900:00Chirping growing more numerous as the night progressed. Only chirping when wavescope was turned off in the APC Gui.
420400:06-00:10, 08:38-08:3900:05Tried to start the CWFS pipeline and got an error of "device off line". PAS LED green in the TCS Gui. Other cameras starting pipeline and images as well as stopping them just fine. Stopped images and pipeline on all cameras, then shut down and restarted the pas server only, which fixed the problem.
437223:48-00:5901:11Got error while going to satellite GOES 14 during check out test from Matthew. After this error any movement of the structure resulted in an error and the structure would not set down unless stop was hit in legacy tab. See errors and detail in PR. Called: Randy

Randy came up and adjusted the legacy code which fixed the problem.
413506:37-07:0100:24uptime: 45385.5 HFC fault in the middle of a trajectory right after a focus adjust of 0.2 mm. In the tracker status tab the last error reads "MSG LX Track Motor Current Fault". Much more detail in PR. Final solution was to restart dspace and cycle the power in the power cabinets (turn breakers off then back on after a few seconds). Start servers and tcs gui and reinitialize the tracker.


Ops Commentsnone


TO CommentsWeather was calm and clear all night. Seeing was ok and stable. Temperatures were pretty steady.


RA CommentsWe collected 3 sets of data for the DWFS8-CWFS calibration. We tested the RA and DEC setups without success. We were able to center up several stars on the WFS2 with a known position on the ACQ. This allowed us to determine the offsets and get a GSS onto WFS2 at the end of the night.
