Dembicky We started the night off with clouds, so I held off on opening the enclosure until conditions improved. We have a big system to the South and it looked like it might carry rain in those clouds. I did turn the cooling fans on around 19:00. The clouds thinned a little around 21:00, but still nothing too great to shoot any science thru and my observers were looking for faint targets as well. I did opened the lovers at 21:30 to further help dome cooling. My second half observer did not show tonight. When conditions appeared to be improving (around 02:30) I tried calling him on the only phone number I had, from the program proposal, but got no answer. At 02:50 I opened the enclosure and again tried calling my 2nd half observer, but no answer still. Since I had no other number to call (I don't know if the number on the proposal was work or home, but from the NMSU control room number I have in the control room it looks like a work number.). I tried calling the NMSU control room as well, but nobody was there either. Since I had no numbers other numbers to try, I used the time to take some PR shots with SPIcam and continued to try contacting my 2nd half observer with the number listed one more time. The sky was only marginal at best, with clouds all around us, but still operable. Finally clouds swamped us again at 04:20 and I closed down for the remainder of the night. ------- FAILURE LOG ------- PROG INST FAILURE TIME S/E/G/D/O TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 03:08 SPIcam 120(1005) 105 58 11.3/11.4 298 17 r' 1.01 --------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 17:01 60 14 12 268 (W) 680 Cloudy none 18:01 60 16 11 257 (WSW) 752 Cloudy none 19:01 59 13 8 262 (W) 816 Cloudy none 20:01 52 7 14 234 (SW) 928 Cloudy none 21:01 52 6 17 223 (SW) 845 Cloudy none 22:01 52 7 16 237 (WSW) 979 Cloudy none 23:01 52 6 13 247 (WSW) 918 Cloudy none 00:01 53 7 14 255 (WSW) 666 Cloudy none 01:01 53 7 16 283 (WNW) 617 Cloudy none 02:01 53 7 15 293 (WNW) 500 Cloudy none 03:01 52 6 11 287 (WNW) 566 Pt.
