Date: 
Thursday, November 8, 2012
Telescope: 
CTIO Blanco 4-m
Submitter: 
R Blum
Observer Support: 
Mauricio Rojas
Night Assistant: 
Alberto Alvarez
Also Present: 
D Norman, C Kaleida, A Saha, R Blum
Problems: 
Seeing, wind, clouds. The 4MAP system went out four times. Alberto cleaned the RA tach, but it failed once more after that. The TCS application crashed at the same time at least twice when the 4MAP went out. Not clear how these are related (i.e. which happened first). Night ended with 4MAP failure, but conditions so bad, we did not lose useable time. Leaving without 4MAP fixed. The wind direction sensor is not working. The read out is stuck at constant position.
Comments: 
Difficult night with conditions and TCS/4MAP failures. We found out serendipitously that the hexapod was not on last night for all the community time. As far as we know, no solution found the N30 detector which is having issues.
