Rotator motion aborted when we tried to send it to zero with tcc track and mcp commands. ---=== OBSERVING LOG ===--- Afternoon: Spectrograph focus checked, no adjustment made. No problems to report. 23:50Z Fans on, louvers and east door open, west door craked. Night: We did not open till 11:10Z due to clouds. Instrument lift seems much slower than usual. 11:20Z cart 1, plt 1809 (chunk). Sky is better than hours ago, but still cloudy. Seeing is not bad, about 1.4". Through clouds, we got two good exposures and a BAD exposure. plate is NOT done. Rotator failed to reach zero degree during the closing process with following watcher messages (we tried both tcc and mcp commands.
