Az 44.5 Alt 48.6 UT 04:37:51 Alt servo error UT 04:55:45 Az servo error UT 06:24:31 Az servo error I reset both the Alt & Az controllers at 01:00 local (UT07:00) per Fritz's instructions UT 08:38:30 Alt servo error UT 12:17:37 Alt Servo Error, MIrror covers were closed so it slewed up to about 73 deg alt before I got things restarted. The alt axis gave me another servo error when I went to do the next slew (to park the telescope). I manually moved the telescope down in alt when I closed up. ------------- FAILURE LOG -------------- PROG INST FAILURE MODE TIME (STEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ----------------------------------------------------------------------- 19:40 dis-slit -42( 337) 56 41 12.6 15.3 14.0 13.3 13.8 -- 1.65 19:45 NA2gdr -2188(19812) 55 42 12.8 15.1 14.0 13.8 13.8 clear 1.60 01:18 SPICAM 62( 522) 112 45 12.2 12.0 12.2 11.0 11.8 r' 1.10 01:21 NA2gdr 1305(31305) 112 46 12.3 11.9 12.2 10.9 11.7 clear 1.20 02:16 dis-slit 25( 218) 173 53 12.0 11.8 12.2 11.4 11.8 -- 1.15 02:20 NA2gdr -3000(18999) 174 53 12.0 11.8 12.1 11.3 11.8 R+ND2 0.86 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 60 32 9 355 (N) 567 clear none 17:00 58 32 4 348 (NNW) 564 clear none 18:00 56 32 1 343 (NNW) 613 clear none 19:00 55 31 16 33 (NNE) 582 clear none 20:00 56 30 16 55 (NE) 701 clear none 21:00 54 29 15 66 (ENE) 649 clear none 22:00 56 24 11 36 (NE) 618 clear none 23:00 55 25 10 0 (N) 584 clear none 00:00 55 21 9 0 (N) 572 clear none 01:00 55 27 12 4 (N) 547 clear none 02:00 54 27 1 26 (NNE) 616 clear none 03:00 52 27 10 6 (N) 760 clear none 04:00 52 27 12 11 (N) 613 clear none 05:00 51 27 10 18 (NNE) 601 clear none 06:00 52 22 5 334 (NNW) 565 clear none Note: the wind was coming from the azimuth listed.
