Problems: 

At 00:04, we ran a TCS slew command after finishing a long (12 observation) NEWFIRM script with seqrun.py and the telescope did not slew properly.  It remained at the previous set of coordinates and ignored input from TCS and seqrun.py commands, repeating the previous observation that was taken.

This issue persisted until 00:20 with the NEWFIRM GUI displaying "Performing offset" and no response happening in the telescope position or other values in the GUI.  pressing the stop sequence button did not work.  We resolved the problem by stopping the GUI and restarting.

While running a script, obtained "response format error unknown remaining" during an observation script at UTC 00:00 and 01:25.

TCS slew command did not have telescope response at UTC 01:38.

At the end of the night, the enviromental cover remains open.  It should be closed by hand as soon as possible.

 

Comments: 

The text viewable on the NEWFIRM GUI is extremely small and difficult to read through the Zoom window and it would be preferable to observe with NEWFIRM directly over VNC/VPN.

Another issue is that only one person can operate the Zoom interface at a time, whereas our observing program would be much more efficient with two people accessing the VNC at one time (one to observe, one to analyze data).
