Night Assistant:

Also Present: 
I Chillingaria, V Toptun, F Kolganov
Problems: 

Problems with the guider at the beginning of the night but was resolved by Claudio, Manuel, with help from La Serena (Omar, Manuel M., and/or Rolo? ).  Claudio can explain the fix in his operator report. Shortly before 05:00 UT, we moved to a northern object near the equator with a rotator angle of 17deg.  During acquisition, we lost the guider and tried to restart. Claudio also noted that we lost the rotator at the same time.  Claudio went up to Cass to investigate and saw that two cables in the Cass cage were cut at some point during the acquisition procedure, effectively ending the night.

Cables will need to be repaired tomorrow.  Should also test rotation at Cass to see if there are any other cables that might snap during rotation and try to get some slack in the lines.
