Numerous small problems throughout the night. During checkout test slews error was given upon tcc axis init: "23:18:38 .tcc.0 0 tcc F Modu="prt_Write"; Text="ss$_Hangup: received unsolicited character or ^Y on port LTA4:" Resetting alt in talk2boxes fixed problem. Echelle pointing was off by half arcminute. Corrected with tert tilt. At 00:30 in the middle of exposure sequences NICFPS images turned to all 0's. 'nicfps expose init' corrected the problem for 10 images then all 0's. Restarting the ICS seemed to correct the problem for the next 15 exposures. Resetting the controller seemed to completely fix it until 02:15MT when it occurred again. PR1180 contains more information on these events as well as files names for examples.
