Problems: 

At 5:38 UT we got a warning regarding error transfering image to the comfort display. Indeed the comfort display did not show chips S7, N7, S6, N6, S5 and N5. A few minutes later the Image Builders gave problems. Images affected were 519364 and 519365 (starflats with the N964 filter). These images are being reported for exclusion in the CP. In a first attempt we tried, unsuccesfully, to restart the comfort display. A SISPI restart solved the problem. Time lost: 20 minutes.

GUIs were crashing more than usual during the night.

At 7:55 UT there was an interlock broken due to the Latch. This was due to observer's error who tried to send the telescope to a forbidden position :(

 

 

 

 

Comments: 

Clear night with seeing ~0.8" - 1.2" for most of the night, although there were excursions to 1.5" at some point. Some haze low in the horizon.

We completed the 1h-long Suarez's program, starflats for all 8 filters in the field near Omega Cen, plus some images for project 2016A-0196.
