The arcade fan seem to be working intermittently tonight starting around midnight. Problem report was submitted. At several points during the 2nd half the fan stopped completely for several minutes or more and then would just start back up. I adjusted focus "off the guider" during the first half of the night and the 2nd half focus was stable and did not require anything other than the initial instrument focus . ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 18:34 DISslit 60(1204) 127 69 7.5/7.8 316 11 none 1.0 18:37 NA2gdr -1255(54744) 129 70 7.6/7.8 344 9 R 0.98 00:24 SPIcam 50(1275) 124 68 6.6/6.2 227 14 R 0.67 00:29 NA2gdr 953(49953) 126 69 6.1/6.1 238 13 R 0.86 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 50 6 16 310 (NW) - Mst.
