NICFPS was reading all zero and needed an init and it went to zeros twice more during the night. The second occurance was near 4:30am and the instrument was at a rotation 16 mount (az 43, alt 69. The third time was at 06:15 am after the user made a large rotation (about 75 deg) with the instrument at rot 72 (az 89, alt 80). User had just completed a slew. I added it to the audit trail for PR 1928. Aside from the NICFPS fun, we had a beautiful sky! It was clear all night and the seeing has finally improved from the previous two week and was good to excellent all night. ------- 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 -------------------------------------------------------------------------- 17:39 ecamera 580( -397) 57 82 2.4 3.9 3.8 4.0 2.8 ND1 1.81 19:07 ecamera 426( -658) -73 77 1.3 1.6 2.4 1.5 1.5 Clear 1.28 21:05 tcamera 400( 414) 33 72 0.7 0.4 1.1 -0.1 0.6 Ks 1.10 00:22 NICFPS 359( 611) 68 74 -1.4 -0.9 -0.4 -1.4 -1.3 MKH 0.80 05:26 NICFPS 444( 715) 42 59 1.4 -0.7 0.0 -1.2 0.4 MKH 0.84 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 41 -6 6 103 (ESE) 93 clear none 17:00 37 -9 11 71 (ENE) 103 clear none 18:00 35 -12 20 66 (ENE) 130 clear none 19:00 35 -12 16 43 (NE) 148 clear none 20:00 32 -13 3 208 (SSW) 153 clear none 21:00 33 -12 4 190 (S) 135 clear none 22:00 34 -12 1 151 (SSE) 140 clear none 23:00 33 -12 4 232 (SW) 152 clear none 00:00 31 4 5 163 (SSE) 197 clear none 01:00 29 5 3 122 (ESE) 219 clear none 02:00 30 6 5 198 (SSW) 203 clear none 03:00 30 -1 6 211 (SSW) 114 clear none 04:00 33 -1 6 195 (SSW) 137 clear none 05:00 33 -8 5 259 (W) 168 clear none 06:00 34 -8 5 197 (SSW) 136 clear none Note: the wind was coming from the azimuth listed.
