Problems: 

Telescope misbehaved tonight!:

    * While observing target BU CMii at the beginning of the second exposure (1138), the telescope began to move North-South, I stopped the observation, moved to a close star and the telescope was back to normal.  Then I took the 2 remaining images.

    * 1:08 LT pointing lost, back to observe at 01:52LT.

    * 3:52 LT telescope lost tracking.

I keep seeing the drift to the West, at times even when guiding!

cagvm site for telemetry couldn't be reached at times after ~1:00 LT. We lost access to the noao-south WiFi network intermittently, so that page and others, including the night report couldn’t be accessed from WiFi. 

In the ctiomac3 there was no folder for the night, I created the folder and I set the first science image as 1120. It seems there are no afternoon calibrations.

I got the following error message at the beginning of the night. ”GUI ERROR ON COMMAND EXPM SEND …” I re-started the exposure meter. 

 

Comments: 

Mostly clear night, cirrus close to the horizon during the first half of the night. 

No DIMM tonight, the seeing according to RINGSS ranged approximately from 0.6 to 2+ arcsec.

Targets skipped: HD105004, V1280 Sco  and V5856 Sgr.

Image 1133, wrong object name in the header it should be  TIC0220144363.
