501905:56-05:57, 05:58-05:58, 05:59-06:0100:03Persistent dome-related trajectory aborts (Move to command failed) at south trajectory
501507:52-07:58, 08:45 - 08:5000:11Restarting tcs server because WFS corrections are not going through to DMI or TT. After restart still found that WFS would not make focus or TT corrections. From about 08:45 til 08:50, after more restarts, the same thing happened.Called: Randy

502001:29-02:0000:31Had to realign collimator and lenslet array in CCAS tower.Called: Herman

502108:17-08:17, 08:53 - 08:5300:00Unable to set manual fiducial or stop metrology loop in TT Cam after WFS is activated.
501607:59-08:0600:07tcs server appears to be up and functioning but has no attribute for syscmd help. Using kill -6. After restarting load_trajectory has no attribute. Restarted server normally and it worked. 08:30 again load_trajectory has no attribute after restart, but after another restart it worked at 08:33
500403:39-03:4100:02MARS problem where nothing moves when commanded; for some reasons X Position is +3644 and target is -954. Y position is +3644 and target is -2194. F position is +3644 and target is +3644. I'll check the numbers next time this happens again.
501702:42-03:3800:56Had to redo mirror_alignment.txt file before stacking.
502302:01-02:1900:18Some DMI adjustments made for better readings at CCASCalled: George

502210:40-11:0700:27TT Camera metrology consistently not finding object, even though images look fine.
422409:21-09:2200:01One-off TMCS failed to acquire trajectory error
501802:20-02:4100:21Communications with WFS 1 were down; ascension to tracker required to fixCalled: George
