I had a weird issue during check out during test slews; I had DIS mounted and the rotator wouldn't rotate even thought the axis was initalized. I tried stopping the axes and reinitializing but it didn't help. I flipped the bypass switch on and off and then it was fine. DIS was mounted at the time and, when I mounted it, it wasn't completely at 0 so, before lowering the instrument, but while I was pressed against the rotator I moved the rotator by hand. Maybe that did something?? We started the night with clouds and I was worried they would hang out all night (there were some radar pings nearby) but things cleared up really nicely by 19:00 and we had almost clear skies all night! The seeing could have been better but I'll take the photometric sky. Our UW04 group logged in remotely and the training went great! Granted, Paula Szkody may have strutted in and pointed out some things on their screen, and Hannah is actually already trained but, hey, they did a great job and had a system DOWN in an hour. Which is great because they aren't likely to get much more :( If you're a morning person, go check out the moon! There's a nice alignment of Mars, Jupiter, and Saturn up at dawn with a crescent moon. ------- 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 -------------------------------------------------------------------------- 19:02 dcamera 369( 363) 175 70 3.4 4.9 5.0 4.7 3.6 -- 1.47 19:56 dcamera 406( 374) 18 35 3.4 3.8 4.2 3.6 3.4 -- 1.51 00:20 arctic 459( 521) 52 36 3.2 2.0 3.0 2.5 2.9 VR 1.71 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 41 24 10 263 (W) 127 cloudy none 17:00 40 24 11 270 (W) 147 cloudy none 18:00 38 23 12 241 (WSW) 136 mstly cldy none 19:00 38 24 12 245 (WSW) 162 clear none 20:00 38 21 16 278 (W) 121 mstly clr none 21:00 38 21 12 264 (W) 238 mstly clr none 22:00 38 20 13 269 (W) 253 ptly cldy none 23:00 37 21 18 279 (W) 427 mstly clr none 00:00 37 21 10 278 (W) 482 clear none 01:00 37 20 18 301 (WNW) 417 clear none 02:00 37 20 16 304 (NW) 336 clear none 03:00 37 19 13 313 (NW) 289 clear none 04:00 36 19 4 359 (N) 305 clear none 05:00 37 18 6 355 (N) 289 clear none Note: the wind was coming from the azimuth listed.
