6569	08:55-09:07	00:12	HPF Exposure (Queue #4777) Wouldn't Start after Target Setup Complete in HObs following an Aborted LRS2-R Exposure (Queue #4766)	Aborted the HPF exposure and re-ran target_setup and iexp manually from terminal.
6570	09:46-10:26	00:40	HObs Scheduled Target Observed Earlier in the Night with SYNFREQ = RAND1-2	Didn't catch error until 2nd exposure started, had to wait for full exposure sequence to complete and then moved to next target.
6569	09:07-09:46	00:39	The aborted LRS2-R exposure (#4766) seems to have also caused the PFIP shutter to close once the HPF target (#4777) exposure sequence had started. Shutter remained closed during full exposure sequence.
4683	08:30-08:49	00:19	Trajectory ends after "Failed to send point to TMCS" error.

TO Comments	Clear and calm night with stable temperature.
