↪ CommentsWhile troubleshooting the structure I should have opened the dome to equilize temperature. Newbie mistake. Temps off by 6 degrees (truss and ambient). Focus curve did not look very good tonight either. Tried to run it twice (perhaps bad dome seeing).

23:51-02:2602:35During check out test (new test proposed by Matthew at beginning of the night). I sent a trajectory and the structure never made it to correct azimuth as well as the go_next command never turned green. Errors and details in PR.Called: Randy

Randy came up and worked on it for awhile and got us back going for the night. I then restarted the servers and gui and was able to start successfully stacking. Restarting servers and gui at this point also fixed the failed to adjust trajectory problems.
169603:17-03:1700:00Removed sensor 88-1 for LTRSE.
413503:27-03:2800:01While stacking I got a HFC Fault trying to move the tracker to the left bottom corner preset. Temp outside 0.8C.Tried to reset the fault and move it again. This worked.
436705:36-05:40, 08:05-08:05, 09:09-09:1200:07Tried to start loop on TT camera and could not. See error in PR. Canceled the trajectory, Shutdown guis and servers and brought them back up and reacquired the trajectory. This worked for only the first trajectory then the error came back. Received this a couple more times. See PR.
350106:44-06:4700:03While trying to focus for stacking, the DMI stage would not come back out when pressing the out button. Solution was to put the HEFI mirror in and the DMI stage moved out automatically which fixed it.
436806:13-06:1300:00Hit stop images right after hitting cancel trajectory and this caused the tcs gui to hang.Shutdown servers and killed the gui, then restarted it all back up. This worked to solve the problem.
436906:28-06:2800:00Cameras taking a long time to update frame and settings. See PR.
422506:35-06:37, 08:36-08:36, 09:48-09:4800:02HFC fault while canceling trajectory. Details in PR.Reset faults and was able to send the tracker to right the correct place.
420405:42-05:5000:08While trying to start CWFS Pipeline back up got the "pasPipeline_StartPipeline failed; device off line" error. Other cameras seemed to be working fine. Error listed in PR.Shut down the pas server and restarted it. Which fixed the problem
413508:06-08:1100:05uptime: 50775.9 HFC fault in the middle of a trajectory. It still looks in the gui like there is a current trajectory, but when you hit cancel it says no current trajectory. Trying to abort doesn't change it either. See screen shot and solution in PR.Shut down servers and gui and restarted them.
434309:02-09:0200:00Still unable to see the extra focal tests clearly on monitor with gain all the way up. It is a little better though and the high gain did not seem to affect the stability of the camera.

TO CommentsProblems at the beginning of the night. Due to the new check test we were able to get working on the problems almost an hour before sunset. Clear most of the night but seeing was not that great.
