We opened first at 20:30, and after not getting any data or guide stars through the clouds, we closed at 21:20. During the time we were open, we got not data, so I listed this as time lost to weather. We opened again at 23:11, and stayed on sky the rest of the night. At 05:04, UC02 alerted me that his latest image was blank. Looking into it, we found that images 23-30 were blank. /Q3UC02/UT130826/estar00**.fits He began image 23 at UT 10:07, and I found a message in the log: 10:18:14 UC02.don.echelleExpose 1330 echelle f text="no exposure is active." UC02 and I did not notice until this time, and after I attempted a hub startNubs with echelle, he elected to discontinue his exposing, and retire for the night. I do not have an explanation for this- I have a suspicion that it was a hangup with the icc, but I could not reboot it in time to continue science. This stopped science from 10:07 onward, so I logged that time down to equopment failure. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- UC02 ECHE I/S 04:04 06:26 echelle not writing images, all blank ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:59 ECHELLE 496( -133) 148 72 14.6 15.2 15.3 15.2 14.4 clear 1.50 01:17 dis-slit 504( 802) 291 81 12.7 12.8 13.2 12.8 12.4 -- 1.86 02:50 ECHELLE 594( -151) 196 35 12.2 12.1 12.5 12.2 11.9 ND2 1.99 04:50 ECHELLE 650( -120) 248 46 12.4 11.9 12.3 11.9 12.1 ND2 1.14 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 62 47 10 112 (ESE) mstly cldy none 17:00 61 47 12 122 (ESE) ptly cldy none 18:00 60 47 14 112 (ESE) mstly cldy none 19:00 59 48 16 108 (ESE) mstly cldy lt rain 20:00 59 47 14 110 (ESE) ptly cldy none 21:00 58 48 17 95 (E) mstly cldy none 22:00 57 49 20 116 (ESE) cloudy none 23:00 57 49 23 112 (ESE) cloudy none 00:00 56 49 20 80 (E) mstly cldy none 01:00 55 49 15 87 (E) ptly cldy none 02:00 54 50 12 92 (E) mstly clr none 03:00 54 49 15 83 (E) mstly clr none 04:00 54 49 14 81 (E) clear none 05:00 54 48 11 82 (E) clear none 06:00 54 49 13 80 (E) clear none Note: the wind was coming from the azimuth listed.
