06:51 UT -- Started observing on M33-LBVptf. Airmass 1.12, seeing 0.57".

08:20 UT -- Some clouds overhead, seeing holding below 0.8". Finished observing on M33-LBVptf. Slewing to M33-VarC.

08:26 UT -- Acquiring on M33-VarC. Seeing suddenly jumped up above 1.2".

08:30 UT -- Tried observation on M33-VarC. The script caught an error with "Command 'PARTNER AZ' timed out after 30 seconds"

08:32 UT -- Re-tried observation and it succeeded. Observing on M33-VarC. Airmass 1.53, seeing 1.3".

09:12 UT -- Received error from MODS2 dashboard that dewar pressure exceeded 0.001 torr. Pressure went back to normal range within ~40 seconds.

09:30 UT -- Finished observation on M33-VarC. Slewed to standard star G191-B2B.

09:37 UT -- Started standards on G191-B2B. Airmass 1.10, seeing 0.68".
