Problems: 

The software controlling the lamps from the instrument control interface crashed twice. This was resolved by restarting the ARCoIRIS gui.

After specifying an exposure time of 120 seconds, the actual exposure times for the observations in the sequence were 19.25 seconds, the minimum possible exposure time for Fowler 16. The filenames that were affected by this issue are YSO_163957_480248 -sequence 255 to 258 (an ABBA cycle). This problem self-corrected for the next sequence of observations.

 

Comments: 

It would be useful to have an M4 status window.
