Problem Reports

437623:35-23:4000:05While doing the check list we sent a target at 1454542655 (date +%s) and the structure and tracker started to move. The structure set down at the correct azimuth but the tracker never started to track on the sky.Waited till after the roll over to try another target. Tried to send a target later and TCS server was hung at 200% cpu usage according to top. Shutdown tcs server and restarted it.
392404:13-04:1500:02Due to cold we are hitting the lower limit of the Y stage and are unable to line up the AOA return spots with the reference spots while stacking. Unable to complete a stack unless the night warms up.
422508:09-08:12, 08:57-08:5700:03HFC fault while cancelling trajectory. No error displayed.Checked the skew value since it was below -4C in the dome. Tracker was not skewed so just reset the fault and sent another target.


Ops Commentsnone


TO CommentsCold and clear tonight. Temperatures reaching around -5C.


RA CommentsVery clear with low winds at sunset. Did dwfs8+cwfs eng tests until cold temps (<-3C) prevent restacking needed for such tests. Spent remainder of night doing engineering tests not sensitive to GRoC issues.
