During the first half of night we closely monitored clouds and humidity, but everything stayed copacetic for operation. The seeing got noticeably worse around 22:30 but improved by the end of the first half of the night. Changes in conditions corresponded to rapidly changing wind directions back and forth between E -> N -> NW and back again throughout the night. We had no motion errors tonight, but there were a few ~1amp oscillations in the alt current strip chart (and corresponding higher amplitude T Load Cell) with no noticable impact on imaging. Training for Amanda: - Focusing with Arctic - How to mount an eyepiece - Humidity variations - Loading star catalogs - Different instrument guiders - Filling the TSpec aux tank - Non-sidereal tracking ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:49 arctic 453( 1013) 81 61 11.4 13.0 12.9 12.2 11.4 sdss-i 1.16 22:39 arctic 486( 906) -15 71 7.7 10.1 10.7 10.2 8.2 sdss-i 1.83 02:41 ecamera 465( -339) 59 81 8.8 7.5 8.2 7.4 8.1 Clear 0.80 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 63 32 28 218 (SW) mstly cldy none 17:00 47 32 16 83 (E) cloudy rain 18:00 47 32 21 85 (E) cloudy none 19:00 45 32 14 80 (E) ptly cldy none 20:00 50 31 4 52 (NE) mstly clr none 21:00 52 31 2 337 (NNW) mstly clr none 22:00 52 30 16 63 (ENE) ptly cldy humid 23:00 44 32 20 63 (ENE) ptly cldy humid 00:00 43 31 16 61 (ENE) ptly cldy humid 01:00 45 31 1 348 (NNW) mstly clr humid 02:00 47 31 7 9 (N) clear humid 03:00 49 31 1 327 (NNW) clear none 04:00 49 30 6 311 (NW) clear none 05:00 49 30 1 269 (W) clear none Note: the wind was coming from the azimuth listed.
