Weather was snowy and cloudy all night. Started the snow program at 1930 because snow started to accumulate again. Mark practiced mounting NICFPS. We also reviewed the limited rotation range aspect. After being moved the NICFPS exposure had black and white bars and required nicfps expose init as per the wiki, and that fixed it. Russet noticed the roof heaters were not producing heat even though they were turned on. Amanda found the breaker was in the OFF position and switched it ON. We set up Mark's obsA account and several utility programs. We restarted the stripchart mac since the charts were frozen (showed 100% CPU usage). Stopped snow program at 01:00 to home secondary due to a discrepancy between the encoder and commanded values. Restarted snow program at 02:30 and stopped it again at 4:30 when we gave up for the night. Near the end of the night, test dark failed on NICFPS with UNPARSEDTEXT="ERROR: Setting exposure time failed -> 0x455252", nicfps expose init resolved the issue. Parked at 104,84 for LN2 transfer. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 30 27 8 207 (SSW) cloudy humid 17:00 29 27 6 226 (SW) cloudy humid 18:00 29 27 3 202 (SSW) cloudy fog 19:00 29 29 9 225 (SW) cloudy lt snow 20:00 30 30 9 187 (S) cloudy snow 21:00 32 31 14 199 (SSW) cloudy snow 22:00 32 30 14 186 (S) cloudy fog 23:00 32 29 6 262 (W) cloudy lt snow 00:00 31 28 10 259 (W) cloudy snow 01:00 32 29 10 214 (SW) cloudy lt snow 02:00 33 28 9 252 (WSW) cloudy snow 03:00 32 28 12 194 (SSW) cloudy snow 04:00 32 28 11 241 (WSW) cloudy fog 05:00 32 28 12 254 (WSW) cloudy fog Note: the wind was coming from the azimuth listed.
