Problems:
At 05:00 we moved to RA=310, Dec=-1.5 to observe YSE field 440. Midway through exposure 991138 (YSE 440.C i-band) the telescope lost its position and we needed to stop the queue. Claudio checked and cleaned the telescope encoder tape and we attempted to try another observation at this location at 05:30. The telescope again lost its position and we stopped. We recovered at 05:38 and tried moving to RA=8, Dec=-43 on another exposure (E12 in program 2019A-0065) and lost the position a third time. Claudio again moved the telescope manually and we were able to recover and move to RA=8, Dec=-43 at 05:50.
