Winds were borderline for much of the night, but of course they would drop just as I got ready to close. The first half observers ended a few minutes early, so I took the opportunity to check collimation with Agile before the upcoming engineering. APOLLO had no success in the windy conditions, getting worse as the moon tracked from east toward the south, so I ended that a little early also and went on to the next program instead, with a target in the Northeast well away from the wind. During second half we had some poor tracking on a target moderately high (70-80 deg) in the northeast; since tracking had previously been fine in this region I suspected a freshly-squished moth, but the observer preferred to put up with the imperfect tracking rather than lose time to clean the drives. With some manual supplementation of the guiding, we were able to keep up. The tracking never became completely unmanageable, and the slip bit was not triggered. ------- 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 -------------------------------------------------------------------------- 23:01 APOLLO 0( 796) 58 63 0.6 0.9 1.1 0.5 0.6 1.70 23:58 ECHELLE 82( -903) 137 74 0.5 0.3 0.6 0.0 0.1 ND3 1.00 00:31 TSPEC 100( 347) 161 78 0.1 0.0 0.2 -0.3 -0.2 Ks 1.10 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.
