Az 163 deg. I suggested guiding with the slitviewer if thing appeared to be drifting. I noted that the slitviewer seemed to stop guiding on the original star and moved to another, not sure if they selected a 2nd star or it did it on it's own. See na2 guider images 170-225. Frame 220 was where it jumped to the 2nd star. Pointing check (04:28MST) Tip-Tilt Corrections were 141 -372 (implemented) Switched to Echelle (NA1) at 06:05, pointing was off. Start tip-tilts 1509 -1069 Final tip-tilts 1746 -1437 (implemented) Change 237 -368 No telescope problems otherwise. ------------- ACTIVITY LOG -------------- PROG INST FAILURE MODE TIME (STEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ----------------------------------------------------------------------- 18:19 AGILE -50( -733) -8 62 -0.5 0.3 -0.0 -0.5 -0.5 BG40 1.06 18:20 NA2gdr 2048(11000) -8 62 -0.4 0.3 -0.0 -0.5 -0.5 clear 0.90 18:34 ECHELLE -263(-1401) 56 65 -1.8 -0.8 -1.5 -3.0 -2.1 ND3 1.07 20:03 dis-slit -79( -569) -1 67 -2.3 -1.8 -1.9 -2.8 -2.2 -- 1.40 20:07 NA2gdr 1698(23698) -4 67 -1.8 -1.8 -1.8 -2.8 -2.1 clear 0.98 20:11 dis-slit -76( -565) -6 67 -1.8 -1.8 -1.7 -2.7 -1.9 -- 1.25 00:15 dis-slit 16( -516) 174 64 -2.4 -2.7 -2.4 -2.9 -2.5 -- 1.03 04:27 dis-slit -21( -446) 130 85 0.5 -0.5 0.1 -0.8 0.3 -- 2.01 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 30 1 9 7 (N) 497 clear none 17:00 29 0 12 20 (NNE) 560 clear none 18:00 27 0 11 19 (NNE) 654 clear none 19:00 30 -9 13 11 (N) 787 clear none 20:00 28 -8 6 17 (NNE) 853 clear none 21:00 28 -12 15 8 (N) 742 clear none 22:00 28 -10 17 29 (NNE) 708 clear none 23:00 28 -7 10 24 (NNE) 659 clear none 00:00 27 -4 22 3 (N) 611 clear none 01:00 27 -3 13 13 (NNE) 598 clear none 02:00 26 -3 11 4 (N) 552 clear none 03:00 31 -10 20 39 (NE) 540 clear none 04:00 32 -8 10 39 (NE) 386 clear none 05:00 33 -6 9 57 (ENE) 175 clear none 06:00 37 -9 2 176 (S) 161 clear none Note: the wind was coming from the azimuth listed.
