There didn't seem to be a precipitation threat so I allowed APOLLO to operate. The clouds also seemed to be thining from earlier. AD02 program didn't get anything useful due to clouds, but we were open during their time. I am going to call the time as weather as it really wasn't useful conditions and we were just open because APOLLO could observe thru them (although not sure how many of their photons they got back eitehr). We were just open becaue there was no precip threat. The clouds finally started to move out around 23:30 and I re-opened shortly after (we had closed at the program change due to clouds and the observers wanted dome cals, it was pretty cloudy outside). Rest of the night went smooth. Testing NICFPS wedges NICFPS horizontal wedge (from right side) focus @ 1500 steps, Images in nicfps subdir Tested with 7.7 mag star in J (star2) Wedge tip 463,356 Sweet spot 483, 356 (20 pixels from tip) Tested with Arcturus Vertical wedge (from bottom) focus @1600 Tested with 7.7 mag star in J (star2) wedge tip 490,345 sweet spot 490,305 Tested wedge with Arcturus. The base of this wedge isn't as thick as the horizontal At the end of the night, the NA2 rotator refused to rotate to 0 when I parked (same as Tuesday). ------- 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 -------------------------------------------------------------------------- 18:56 APOLLO 625( 1570) 64 53 8.1 10.5 10.3 10.6 10.0 -- 1.10 19:42 arctic 758( 891) 122 64 7.6 9.5 9.7 9.4 9.2 sdss_r 0.78 21:58 arctic 783( 838) 197 79 8.5 8.1 8.7 8.1 8.1 sdss_r 0.77 03:58 NICFPS 800( 1207) 252 65 8.3 8.0 8.5 8.3 8.3 J 0.50 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 45 16 7 280 (W) 413 clear none 17:00 41 10 6 286 (WNW) 466 clear none 18:00 42 8 14 290 (WNW) 466 clear none 19:00 43 -1 6 353 (N) 466 clear none 20:00 40 -6 3 333 (NNW) 466 clear none 21:00 39 -6 6 8 (N) 466 clear none 22:00 41 -4 1 242 (WSW) 466 clear none 23:00 40 -4 1 297 (WNW) 466 mstly clr none 00:00 42 -3 2 248 (WSW) 466 mstly clr none 01:00 41 -4 5 258 (WSW) 466 mstly clr none 02:00 42 -2 3 252 (WSW) 466 mstly clr none 03:00 41 -5 6 255 (WSW) 466 mstly clr none 04:00 39 -6 4 254 (WSW) 466 mstly clr none 05:00 40 -5 6 254 (WSW) 466 mstly clr none 06:00 40 -6 5 255 (WSW) 466 mstly clr none Note: the wind was coming from the azimuth listed.
