Problems: 

06:18 UT RA tracking is lost, while integrating on PM04574+1356, +14 degress North declination! Only RA, DEC is OK. This is what Rodrigo Hinojosa described last November 4. I believe the first 2200 seconds of the integration 1157 are OK. HA was like 15 minutes East.

Comments: 

 

Stopped AU Mic at integration # 39, HA>5 airmass 2.35

PM04574+1356 was beyond limits: I did waited until 4 UT (lost 35 minutes; did 5 tries before but dome disconnects.) 

Thanks to Humberto Orrego who found the evaporator of the AC unit was covered by an ice sheet.
