Night ----- When I opened a logTool, I got a failed to execute command: see problems section for error message. We had high humidity at sunset. We closed the doors/louvers and turned off the fans. The heater in the lower enclosure is turned on. 02:00Z Humidity was no longer a problem. However, the clouds still remained. 02:41Z We mounted the imager, open the doors/louvers, and turned on the fans again. And, we waited because of clouds. 04:19Z Humidity was too high again. We closed the enclosure's doors/louvers and turned off the fans. 11:03Z We closed for the night; endNight finished adn was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5706 20:24Z 20:46Z 100 O 33.87 39.33 46 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 34209, plate -9999 ------- 20:24 34209 0.0 bias 20:27 34210 0.0 bias ----- sequence 34211, plate 2060 ------- 20:51 34211 10.0 flat 20:53 34212 2.0 arc 20:58 34213 2.1 arc 21:01 34214 2.1 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 20:26Z 7 0 1.00000 0 1257 0 121 30.2 9.1 26 259 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 19:47Z 42 35 27 259 (W) -9999 - 20:20Z 48 38 26 258 (WSW) -9999 - 20:52Z 46 35 25 250 (WSW) -9999 - 21:24Z 45 32 31 266 (W) -9999 - 21:54Z 46 32 17 267 (W) -9999 - 22:24Z 45 32 25 264 (W) -9999 - 00:27Z 38 33 10 301 (WNW) -9999 - 01:01Z 38 32 19 355 (NNW) -9999 - 01:33Z 38 30 22 314 (NW) -9999 - 02:09Z 38 29 17 264 (W) -9999 - 02:41Z 38 27 16 279 (W) -9999 - 03:14Z 37 28 21 269 (W) -9999 - 03:46Z 36 30 15 294 (WNW) -9999 - 04:22Z 36 31 23 280 (W) -9999 - 04:54Z 35 33 15 307 (NW) -9999 - 05:26Z 34 33 14 300 (WNW) -9999 - 05:58Z 35 32 14 309 (NW) -9999 - 06:35Z 36 29 17 282 (WNW) -9999 - 07:07Z 35 31 15 276 (W) -9999 - 07:39Z 35 30 14 284 (WNW) -9999 - 08:11Z 34 31 14 285 (WNW) -9999 - 08:43Z 34 31 15 283 (WNW) -9999 - 09:15Z 33 31 14 281 (W) -9999 - 09:48Z 33 31 14 273 (W) -9999 - 10:20Z 33 30 15 283 (WNW) -9999 - 10:52Z 33 29 12 277 (W) -9999 - ---=== TELESCOPE STATUS ===--- 23:45Z Doors and louvers cracked, fan on 00:20Z Doors and louvers closed, fans off 02:41Z Doors and louvers cracked, fan on Telescope at 121,30,00 mount LN2 connected and turned on.
