Also Present: 
Alex Drlica-Wagner, Jan Kleyna, Humberto Orrego
Problems: 

07:06 UT – Interlock DECam alert. Possible SHUTTER Synchronization Problem. Can't communicate with shutter.
Alberto called Humberto and he came to the Control Room to investigate the issue.
Issue is solved when pointing to the Zenith but persisted when we moved the telescope back to our field.
Humberto and Alberto restarted the shutter and the architect console.

While writting the night report and adding the last program of the night, I realized that the PI of the last program of the night had a typo in his propid number (128175 instead 126175). The issue was solved by changing the propid in the script. SISPI didn't complain about the bad propid embedded in the script in any moment and always throw the shutter syncronization problem and it wasn't obvious to identify it.

I have added 1.5 hours lost due to other problems.
