We had a couple more black and white images that nicfps expose init fixed, but at 03:34 in the middle of a sequence the images started coming back bad. The NICFPS ICC computer in the computer room was frozen and had to be restarted, and then when trying to restart ICS the ICS gave a 'Software caused connection abort' error, so I had to also fix the hung port. After this, restarting the ICS worked and we were able to begin observing again. The telescope slipped from 80 to 80.2 when I engaged the stop button at the end of the night (with mirror covers open) In spite of the clouds we had sub-arcsecond seeing most of the night. Happy halloween! ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- BY05 NICFPS I/S 02:34 03:35 NICFPS computer froze ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 18:23 APOLLO 350( 1479) -16 29 4.7 7.8 6.9 8.8 5.2 530 1.20 19:32 ecamera 271( -501) -120 69 5.2 6.0 5.6 5.4 5.1 Clear 0.64 01:13 NICFPS 339( 959) -97 58 4.2 3.5 4.3 3.5 3.7 MK-H 0.69 04:58 NICFPS 390( 923) 96 72 4.3 1.9 3.7 2.8 3.2 MK-H 0.67 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 44 26 0 263 (W) 742 mstly clr none 17:00 46 25 5 275 (W) 694 mstly clr none 18:00 41 24 5 355 (N) 691 ptly cldy none 19:00 40 19 7 11 (N) 501 ptly cldy none 20:00 41 20 11 32 (NNE) 493 mstly cldy none 21:00 42 14 9 21 (NNE) 345 mstly cldy none 22:00 42 9 6 13 (NNE) 288 mstly cldy none 23:00 39 16 8 27 (NNE) 427 mstly cldy none 00:00 40 21 4 353 (N) 572 ptly cldy none 01:00 40 23 1 340 (NNW) 639 ptly cldy none 02:00 40 23 1 345 (NNW) 657 ptly cldy none 03:00 39 22 4 269 (W) 554 mstly clr none 04:00 40 21 6 288 (WNW) 602 mstly clr none 05:00 40 21 5 304 (NW) 549 mstly clr none 06:00 40 21 2 305 (NW) 504 mstly clr none Note: the wind was coming from the azimuth listed.
