Lots of cloud, moon, and a brisk east wind would have made it marginal at best in any case. Note: Imager grade 5 nitrogen is down to 300 PSI. The cloud camera seemed to work tonight. ---=== OBSERVING LOG ===--- 00:30Z Doors Open, Louvers Open, Fans On. Dew point split 4.5 C. 00:45Z Temperature dropping, dew point rising, split now below 4 C, moderate east wind. Not a promising trend at sunset. 01:05Z Dew point split 2.8 C. Doors/louvers Closed, Fans Off. Cloud camera seems to be working okay tonight. 10:30Z Dewpoint split remained between 1.8 and 2.8 all night. With about an hour to go before twilight, rather threatening looking low cumulus clouds began forming. 10:50Z We called it quits. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 ---=== 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:14Z 56 41 13 75 (ENE) 344 - Cirrus 22:46Z 55 41 12 91 (E) 361 - Partly Cloudy 23:18Z 55 41 10 110 (ESE) 421 - Partly Cloudy 23:51Z 53 42 13 82 (E) 503 - Cirrus 00:23Z 51 43 14 112 (ESE) 513 - Cirrus 00:55Z 50 44 11 95 (E) 517 - Cirrus 01:27Z 49 44 14 87 (E) 604 - Cirrus 01:59Z 49 45 19 88 (E) 645 - Cirrus 02:32Z 49 45 16 93 (E) 671 - Cirrus 03:04Z 49 45 13 104 (ESE) 673 - Cirrus 03:36Z 49 45 17 103 (ESE) 691 - Thick Cirrus 04:08Z 48 45 17 113 (ESE) 674 - Thick Cirrus 04:40Z 48 45 12 89 (E) 686 - Moderate Cirrus 05:13Z 48 45 18 112 (ESE) 641 - Thick Cirrus 05:45Z 48 45 25 133 (SE) 633 - Thick Cirrus 06:17Z 48 44 22 121 (ESE) 561 - Moderate Cirrus 06:49Z 48 44 19 117 (ESE) 624 - Moderate Cirrus 07:21Z 48 44 18 128 (SE) 581 - Cirrus 07:53Z 48 44 28 124 (SE) 549 - Cirrus 08:25Z 48 44 28 128 (SE) 534 - Cirrus 08:58Z 48 43 20 125 (SE) 548 - Cirrus 09:30Z 48 43 24 133 (SE) 601 - Cirrus 10:02Z 48 43 21 133 (SE) 537 - Cirrus 10:34Z 47 42 21 139 (SE) 524 - Mostly Cloudy ---=== TELESCOPE STATUS ===--- 00:30Z Doors and louvers Open, Fans On. 01:05Z Doors and louvers Closed, Fans Off.
