We were not able to open until 22:23 but were only open 27min before we had to close again. We reopened at 00:00 and AD02 were kind enough to donate 15min of their time to JH01 so he could get one target exposure and I modified the scheduled time accordingly. We struggled with humidity all night but were able to remain open with good seeing and mostly clear skies. NM01 finished his targets early at 04:30 and I used the remaining time until dawn for various engineering work to work on my offsets and test out the arctic focus script. Tspec was bad again today and I tried a power cycle at 18:00 and left it off until 22:30, hoping that the long sit would help. The first few images were bad but later images were good, which lasted about an hour before becoming corrupted again. There were many problems with ARCSAT tonight. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 21:32 ecamera 921( -56) 159 60 9.9 11.2 11.8 11.0 11.1 ND3 1.30 23:38 arctic 650( 833) -67 34 10.2 10.1 10.7 9.8 10.1 sdss-r 1.03 01:18 arctic 675( 831) -11 71 9.8 10.0 10.6 10.0 10.0 sdss-r 0.80 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 52 46 11 323 (NW) cloudy humid 17:00 53 50 9 286 (WNW) mstly cldy humid 18:00 51 49 1 221 (SW) ptly cldy humid 19:00 49 47 1 267 (W) mstly clr humid 20:00 48 47 6 346 (NNW) clear none 21:00 48 45 6 357 (N) clear humid 22:00 47 46 8 9 (N) clear humid 23:00 48 47 6 353 (N) clear humid 00:00 50 43 4 13 (NNE) 150 ptly cldy none 01:00 51 37 8 325 (NW) 81 mstly clr none 02:00 52 38 8 334 (NNW) 115 clear none 03:00 49 43 5 345 (NNW) clear none 04:00 49 41 5 350 (N) 129 clear none 05:00 49 44 5 343 (NNW) clear none 06:00 50 42 4 269 (W) 141 clear none Note: the wind was coming from the azimuth listed.
