Dembicky I started cooling (dome closed) around 17:00. Humidity started creeping up around 18:00 and by 19:00 it was over the closure limit. We also had clouds so I was in no hurry to open under these conditions. Humidity started to drop around 22:00 and I was opened and on the sky around 22:30. Rene noted that the Red spectrograph arc lines seemed wider than a month ago (4.5 pixels FWHM). He was wondering if focus had chaged. The blue lines seemed fine. At the end of the night the arc lines for Red were just a little over 3 pixels FWHM. Not sure why it was changing during the night? PR submitted. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 22:34 SPIcam -50(842) 51 71 4.3/6.2 169 4 r' 1.2 22:40 NA2gdr -2242(30757) 48 72 4.4/6.2 158 3 R 1.2 00:07 SPIcam 25(946) -63 41 3.3/4.5 105 4 r' 1.7 00:59 DISslit -25(691) 36 51 4.7/4.5 161 7 none 1.6 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 55 31 11 209 (SSW) -- Mst.
