We had a beautiful, clear night with good seeing. The UVa class (part 2!) finished their first night on sky and did a fantastic job! At 05:53 am we had some weird power flickers and the telescope stopped mid slew due to collision at position 24.8, 50. I had to power cycle the dome controller and push the telescope off the collision point and then everything was fine. No time was lost since we could take sky flats at the position we were stuck. The mirror covers needed to be reset as well. I did not file a PR. ------- 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 -------------------------------------------------------------------------- 17:30 ecamera 706( 291) 196 39 6.8 8.9 9.5 8.2 7.6 ND3 0.94 23:58 tcamera 424( 1152) -36 67 7.4 6.9 7.6 7.0 7.1 Ks 1.22 01:55 dcamera 499( 834) -48 36 7.0 6.1 6.7 6.0 6.4 - 1.21 03:13 AGILE 385(-1306) 2 61 6.7 6.1 6.8 6.2 6.3 sdss_r 0.91 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 49 17 9 245 (WSW) 730 clear none 17:00 45 16 3 251 (WSW) 862 clear none 18:00 45 7 8 342 (NNW) 357 clear none 19:00 45 4 6 347 (NNW) 375 clear none 20:00 44 3 5 0 (N) 460 clear none 21:00 45 0 9 346 (NNW) 471 clear none 22:00 46 -2 10 8 (N) 551 clear none 23:00 48 1 6 2 (N) 466 clear none 00:00 46 10 7 304 (NW) 497 clear none 01:00 45 10 13 4 (N) 398 clear none 02:00 45 14 7 36 (NE) 474 clear none 03:00 45 13 12 11 (N) 433 clear none 04:00 44 10 13 355 (N) 343 clear none 05:00 42 10 7 344 (NNW) 408 clear none Note: the wind was coming from the azimuth listed.
