Stars are in focus here. Perhaps it needs to be homed? We are missing the filters but that was an easy fix. Dust counts again tonight started climbing around midnight. I kept an eye on things. Like last night, not sure where the dust is coming from. It was elevated all 2nd half but we stayed open. I changed fan configuration to try to keep dust out of the dome. We never hit 6000cts outside tonight but came close at the very end of the night and it was elevated about 4000cts all 2nd half. ------- 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 -------------------------------------------------------------------------- 19:42 ecamera 512( 521) 113 66 17.2 18.3 18.1 17.8 17.7 ND1 1.00 21:15 ecamera 456( 404) -7 40 16.7 16.6 17.1 16.6 16.5 Clear 1.12 01:14 arctic 385( 1283) -85 71 14.7 13.9 14.6 13.9 14.1 J-C_B 1.09 01:16 NA2gdr 35528(35528) -85 70 14.8 13.9 14.6 13.9 14.1 clear 1.13 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 65 52 3 200 (SSW) 3230 ptly cldy none 17:00 69 54 5 214 (SW) 2935 ptly cldy none 18:00 64 48 1 250 (WSW) 2763 mstly clr none 19:00 63 49 6 36 (NE) 2939 clear none 20:00 62 44 10 83 (E) 1477 clear none 21:00 63 42 19 66 (ENE) 1435 clear none 22:00 60 48 14 84 (E) 2338 clear none 23:00 60 47 15 83 (E) 2769 clear none 00:00 58 47 9 89 (E) 3319 clear none 01:00 58 47 16 79 (E) 4097 clear none 02:00 59 45 22 81 (E) 4858 clear dust 03:00 59 43 15 78 (ENE) 4680 clear dust 04:00 57 42 9 137 (SE) 4337 clear dust 05:00 57 43 11 153 (SSE) 5424 clear dust 06:00 57 43 6 112 (ESE) 5824 clear dust Note: the wind was coming from the azimuth listed.
