Changes zero point @03:20 for ARCTIC. 2nd clear focus in log is just after this change. Arctic throughput stars exp times in () for sdss ugriz PG2213 (30,5,5,5,10) PG2331 (30,2,2,2,5) moonlight PG2336 (30,2,2,2,5) moonlight PG0231 (30,2,2,2,5) During 2nd half we re-observed PG2213 (30,5,5,5,10) PG0231 (30,5,5,5,10) ARCTIC shutter status says closed, even when exposing. We also observed M74 (x,120,120,120,x) M74 (300,300,300,300,300) Filter messed up for images r & i. fixed and retaken M42 (5,5,5,5,5) HorseheadNebula (30,30,30,30,30) FIlled GIFS (and NICFPS) at 04:30 and took hose off GIFS to test hold time. I left TSPEC mounted so they could take doome cals. ------- 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 -------------------------------------------------------------------------- 20:52 arctic 628( 1105) 87 68 13.2 15.2 13.9 14.9 15.1 sdss g 1.00 21:04 arctic 603( 1065) 84 71 13.2 14.9 13.8 14.5 13.8 sdss u 1.07 21:17 arctic 598( 1035) 82 73 12.4 14.5 13.6 14.1 13.4 clear 0.92 21:21 arctic 450( 1029) 81 74 12.3 14.3 13.5 13.9 13.2 clear 0.92 22:29 arctic 357( 882) 13 56 11.8 13.0 13.0 12.7 12.4 sdss r 1.05 00:15 SPIcam 357( 609) 0 63 11.7 11.8 12.2 11.7 11.7 sdss r 1.05 00:23 SPIcam 527( 774) -88 66 11.8 11.7 12.2 11.6 11.4 sdss r 0.84 02:28 arctic 277( 741) -67 31 11.6 11.1 11.6 11.0 11.2 sdss r 1.15 04:54 tcamera 513( 751) 50 58 11.0 10.4 10.8 10.3 10.3 Ks 1.10 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp C Dewp C MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 59 45 10 304 (NW) 407 mstly cldy lt rain 17:00 55 52 4 261 (W) 431 cloudy lt rain 18:00 57 46 5 224 (SW) 407 cloudy lt rain 19:00 52 43 5 262 (W) 370 cloudy lt rain 20:00 50 44 9 12 (NNE) 272 ptly cldy lt rain 21:00 56 39 4 291 (WNW) 385 mstly clr none 22:00 55 39 6 225 (SW) 355 clear none 23:00 53 39 8 186 (S) 396 clear none 00:00 53 38 6 192 (SSW) 545 clear none 01:00 53 34 6 196 (SSW) 592 clear none 02:00 52 33 7 210 (SSW) 572 clear none 03:00 53 33 6 232 (SW) 438 clear none 04:00 52 36 7 330 (NNW) 494 clear none 05:00 52 36 11 328 (NNW) 414 clear none 06:00 53 36 7 342 (NNW) 375 clear none Note: the wind was coming from the azimuth listed.
