The onsite class first half struggled with slow wifi, not only for GUEST logins but also for my laptop on the APO wifi. There were a variety of strange symptoms that were probably attributable to the slowdown. But there was also a guiding problem with ecam that I thought might be caused by a backup running in the middle of the night. The guiding problem resolved by itself, and the connection seemed a bit faster after that. But we might want to give the wifi routers a stress test before the next class comes in another week. Aside from those issues, there were no significant problems with either telescope or any instruments. ------- 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 -------------------------------------------------------------------------- 18:45 ecamera 644( 358) 159 32 10.5 11.5 11.1 11.3 10.5 ND3 0.80 19:49 arctic 500( 1239) 8 59 10.0 10.4 10.6 10.1 10.1 sdss_i 0.65 22:14 ecamera 400( 17) -147 27 10.6 9.4 9.8 9.2 10.4 Clear 1.11 01:26 tcamera 400( 1220) 51 52 10.0 8.8 9.5 8.7 9.2 Ks 1.03 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 53 19 6 309 (NW) 434 clear none 17:00 52 19 3 345 (NNW) 493 clear none 18:00 52 19 3 15 (NNE) 466 clear none 19:00 50 17 10 344 (NNW) 298 clear none 20:00 50 18 9 16 (NNE) 367 clear none 21:00 49 18 9 327 (NNW) 392 clear none 22:00 50 19 8 311 (NW) 496 clear none 23:00 50 17 6 258 (WSW) 540 clear none 00:00 50 18 7 302 (WNW) 905 clear none 01:00 50 18 6 313 (NW) 735 clear none 02:00 50 18 6 298 (WNW) 670 clear none 03:00 50 17 7 315 (NW) 547 clear none 04:00 51 17 2 326 (NW) 590 clear none 05:00 51 17 1 249 (WSW) 557 clear none 06:00 52 17 2 194 (SSW) 543 clear none Note: the wind was coming from the azimuth listed.
