About 5 green LEDs above the black tape on the guage. By 20:00 the LEDs were back to normal so it must have been a wisker on the ion pump. We opened a couple minutes late for APOLLO due to clouds. At the end of the APOLLO program again we had clouds formiing on top of us. I opted to close the mirror covers in hopes that they would break soon and there also didn't appear a threat of rain. We re-opened around 22:50 but clouds quickly moved back overhead, I finally opened at 23:50 and we stayed open for the remainder of the night other than a brief stint of clouds around 05:00. ------------- FAILURE LOG -------------- PROG INST FAILURE MODE TIME (STEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ----------------------------------------------------------------------- 20:18 APOLLO 100( 1437) -6 32 18.6 18.2 17.9 17.3 17.9 -- 1.40 22:57 dis-slit 134( 542) 91 62 16.1 16.4 16.6 16.1 16.3 -- 1.30 02:09 dis-slit 143( 510) 242 45 14.9 15.2 15.3 14.7 14.9 -- 1.35 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 65 51 3 340 (NNW) cloudy rain 17:00 59 54 8 16 (NNE) cloudy rain 18:00 57 50 9 79 (E) cloudy rain 19:00 58 48 16 67 (ENE) mstly cldy none 20:00 64 43 7 44 (NE) ptly cldy none 21:00 63 44 11 73 (ENE) mstly cldy none 22:00 62 45 10 87 (E) mstly cldy none 23:00 61 47 13 85 (E) mstly cldy none 00:00 60 46 12 83 (E) mstly cldy none 01:00 61 45 16 77 (ENE) ptly cldy none 02:00 58 49 18 73 (ENE) mstly clr none 03:00 58 50 12 78 (ENE) mstly clr none 04:00 57 50 9 82 (E) ptly cldy none 05:00 57 52 13 75 (ENE) mstly clr none Note: the wind was coming from the azimuth listed.
