Highly variable seeing. The initial instrument block was completed around 21:30, which went well, then we moved on to some instrument discovery time. They decided the ccd was running a little too warm. Then we switched to DIS for some imaging. We had to power-cycle the NA2 guider at the beginning of the night. There was an error with the way the directories were written. 2nd Half Observing Specialist: R.McMillan Second half remained clear, with decent but unstable seeing for a few hours eventually settling to nice subarcsecond seeing. The half observer had a little trouble because his computer had not updated to Daylight Savings Time. He had moved the clock ahead an hour, but the time zone still said Standard Time -- this messed up TUI's predictions of airmass and so on. All observers should be aware that TUI needs the computer time to match the time zone (including daylight or standard). There was a little alarm when some of our weather readouts (the APO Weather Status page) stopped working a few times. But I was able to get the weather info from a deprecated older source, and it appeared the temperatures were still being updated to the TCC, so it wasn't causing any serious problems. I did notice that our computer galileo also thinks it's still Standard time, which probably explains the timestamps on my emails being off. We followed a target through high southern transit (>82 degrees). Unlike a couple of nights ago, we had a good guide star the whole time, and the image quality was just fine. So the trails the other night might have been a slow drift that proper guiding can compensate for, or it might have been something that only shows up above 84 degrees. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ---------------------------------------------------------------------- 20:05 Agile 425(817) 159 75 10.8 11.9 10.9 11.5 10.9 --- 0.8 23:25 DISslit 25(-21) 22 76 9.1 7.7 7.4 8.1 8.2 --- 1.4 01:20 SPIcam 50(337) -50 71 9.3 8.67 8.24 8.79 9.06 r 0.86 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 55 14 14 329 (NNW) 400 mstly clr none 17:00 54 13 14 327 (NNW) 351 clear none 18:00 54 13 6 284 (WNW) 269 clear none 19:00 53 14 10 357 (N) 274 clear none 20:00 51 13 7 38 (NE) 251 clear none 21:00 46 19 16 71 (ENE) 265 clear none 22:00 46 28 11 55 (NE) 1194 clear none 23:00 48 18 6 18 (NNE) 636 clear none 00:00 50 15 9 327 (NNW) 345 mstly clr none 00:00 50 15 9 327 (NNW) 345 clear none 01:00 49 15 4 258 (WSW) 332 clear none 02:00 48 15 8 294 (WNW) 320 clear none 03:00 46 18 6 265 (W) 385 clear none 04:00 46 21 2 213 (SSW) 510 clear none 05:00 46 18 6 6 (N) 458 clear none 06:00 45 18 5 4 (N) 428 clear none Note: the wind was coming from the azimuth listed.
