Comments: 

There were two incidence of warning issued for exposure 410098 and 410128 last night as "Possible occlusion: TCINTERFACE warning." By eye, none of these images have obvious defects. It would be good to know what triggered the warning. We looked at the difference between the az and domeaz in the telemetry database (which we thought was the trigger) and found 410098 to be -8 and 410128 to be 32, 410095 and 410096 had large differences but no warning was issued.

410705 is useless.  I pressed safe mode while DECam was preparing for the last exposure of the night and the filter changed to 'block' while keeping VSUB on.
