As with previous nights, seeing started out fine and then started to get worse around 10 pm. But this time it stopped getting worse and went back to nice moderate values. Perhaps the strange weather pattern is broken. We had a few failures with the DIS slitviewer shutter, but not nearly as many as the previous night. Perhaps this was because I made more effort to exercise the shutter in between uses, but more likely it was because the temperature was about 4 C warmer tonight. I snuck in another collimation check with Agile this morning to test the quick-check method; this worked in less than five minutes in medium twilight. ------- 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 -------------------------------------------------------------------------- 18:49 dis-slit 130( 364) 208 72 3.0 5.8 4.0 4.6 4.5 1.30 20:26 dis-slit 72( 220) 325 83 3.5 4.1 3.9 3.4 3.8 1.10 01:07 ECHELLE 71( -755) -8 77 5.4 3.6 4.3 3.3 4.0 ND1 1.00 Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 48 30 7 224 (SW) 602 clear none 17:00 41 30 3 254 (WSW) 547 clear none 18:00 39 29 1 256 (WSW) 692 clear none 19:00 38 28 5 2 (N) 693 clear none 20:00 39 28 5 4 (N) 502 clear none 21:00 39 27 5 31 (NNE) 495 clear none 22:00 37 26 3 340 (NNW) 428 clear none 23:00 38 26 9 360 (N) 524 clear none 00:00 41 24 7 37 (NE) 268 clear none 01:00 41 23 10 53 (NE) 209 clear none 02:00 41 25 10 85 (E) 266 clear none 03:00 40 25 8 92 (E) 301 clear none 04:00 41 25 4 138 (SE) 272 clear none 05:00 41 25 8 142 (SE) 234 clear none 06:00 40 26 5 154 (SSE) 312 clear none Note: the wind was coming from the azimuth listed.
