Sprinkles around 19:00. Cleared off and allowed us to open after 21:00. NM04 observers could not slew running TUI v1.4 while Echelle was the set instrument. TUI complains, Text="Move rejected; this instrument has no rotator" (PR 666). They had to revert to an old version in order to slew. We switched over to DIS around 22:40 and after focusing and one target the pointing seemed to be off. Checked the magnesensor errors: They were over 1 arcmin. I slewed away and back and pointing improved. Humidity began rising around 2:45 and became threatening around 3:00. Closed at 3:35 and never opened again. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- NM04 E T/S 21:35 21:45 TUI can not slew w/Echelle ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ----------------------------------------------------------------- 21:52 Echelle 0(22000) 141 35 12.4 13.3 13.2 12.2 12.0 ND1 1.9 22:51 Echelle 0(22000) 218 57 11.5 12.0 12.2 11.0 11.3 1.1 23:53 DIS 0(22000) 190 25 11.1 11.3 11.7 10.6 10.8 2.1 01:29 SPICAM -95( 342) 300 39 10.6 10.6 11.0 10.2 10.5 1.4 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 63 48 19 198 (SSW) 611 ptly cldy none 17:00 62 48 16 207 (SSW) 725 ptly cldy none 18:00 59 44 19 202 (SSW) 645 mstly cldy none 19:00 51 46 2 188 (S) 7030 cloudy dust 20:00 53 49 16 206 (SSW) 1533 cloudy lt rain 21:00 55 41 15 217 (SW) 720 mstly clr none 22:00 53 44 19 216 (SW) 1216 mstly clr none 23:00 53 46 21 223 (SW) 1404 mstly cldy none 00:00 52 42 17 211 (SSW) 454 mstly clr none 01:00 52 42 13 221 (SW) 447 clear none 02:00 51 44 16 229 (SW) 426 clear none 03:00 50 45 12 233 (SW) 572 clear humid 04:00 50 45 13 251 (WSW) 753 mstly clr humid 05:00 50 46 12 261 (W) 975 mstly clr humid 06:00 51 44 10 267 (W) 1152 mstly clr humid Note: the wind was coming from the azimuth listed.
