Worked fine after I shocked it back to like (restarted heartbeat). 06:25 Arctic filter move failed, SDSS_g (#2) to SDSS_i (#3) @ rot 129 deg. 06:43 Arctic filter move failed, SDSS_i (#3) to SDSS_r (#4) @ rot 146 deg. During the midnight transfer to DIS, pointing seemed to be a little off (targets were a little farther below boresight than normal). I did a couple slews and magna sensor dumps, but still seemed a bit off with Feige 34. My observer slewed and pointing was very close to the boresight! YAY! No problems tonight other than the ARCTIC filter moves noted above. ------- 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 -------------------------------------------------------------------------- 17:28 APOLLO 525( 1857) 82 49 6.6 8.4 8.2 8.3 6.8 -- 1.80 18:27 arctic 402( 997) 135 50 7.5 7.2 7.5 6.7 7.1 SDSS_r 0.88 18:30 NA2gdr 3096(37096) 135 51 7.6 7.2 7.5 6.7 7.1 R 1.03 00:23 dcamera 505( 799) 223 55 6.2 5.5 6.1 5.6 5.7 -- 1.57 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 46 -5 4 49 (NE) 91 mstly clr none 17:00 44 -6 8 356 (N) 96 mstly clr none 18:00 45 -12 12 22 (NNE) 68 mstly clr none 19:00 45 -9 17 20 (NNE) 59 clear none 20:00 43 -7 14 29 (NNE) 44 clear none 21:00 43 1 15 27 (NNE) 41 clear none 22:00 43 10 16 15 (NNE) 50 clear none 23:00 44 5 12 26 (NNE) 68 clear none 00:00 43 6 13 4 (N) 81 clear none 01:00 42 9 6 352 (N) 67 clear none 02:00 45 11 6 348 (NNW) 38 clear none 03:00 46 4 8 325 (NW) 58 clear none 04:00 44 5 7 347 (NNW) 75 clear none 05:00 44 9 4 338 (NNW) 51 clear none 06:00 43 14 11 5 (N) 59 clear none Note: the wind was coming from the azimuth listed.
