No April Fools Joke when I say it was a busy night. Evidence most of the night that Azimuth tracking was rather poor with repeated elongated images in unguided fields with nicfps which could not be attributed to focus although secondary focus was changing more than expected right up until 23:00, well after the telescope had reached equilibrium. Adler turned over their time to JH02 when they had troubles logging in tonight and when they discovered that they could not control NicFps from Remark. They instead watched remotely as Leslie collected her data and with he permission showed it to their audience. I did not count their time as used by them but rather by Leslie. I was able to observe 4 Gravitational Lens systems second half before switching to GRB050401, a ToO for the remainder of the night. Lots of good data collected tonight. Fred Hearty reduced much of the GRB data real time from CU. Having him as a copilot tonight was a BIG help. Thanks Fred! ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFNVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 18:58 nicfps 50(1260) 198 77 -0.7/0.9 168 7 MkJ 0.89 20:27 nicfps 125(1346) 269 50 0.0/-0.3 187 4 MkJ 0.82 23:10 nicfps 112(1338) 253 44 -0.2/-0.8 257 1 MkJ 0.57 00:13 SPIcam 100(985) 212 75 0.8/-0.7 259 4 r 0.81 00:21 NA2gdr -1290(35709) 209 40 1.4/-0.5 258 5 R 0.84 01:23 SPIcam 0(996) 298 43 -0.6/-0.5 355 4 r 0.69 02:50 nicfps 200(1426) 152 56 2.1/0.4 257 2 Ks 0.52 03:36 NA2gdr 270(45270) 172 59 2.2/0.6 209 6 R 1.09 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 42 17 5 183 (S) 193 clear none 17:01 37 14 3 205 (SSW) 212 clear none 18:01 33 13 1 185 (S) 204 clear none 19:01 31 13 7 177 (S) 258 clear none 20:01 31 12 5 181 (S) 216 clear none 21:01 32 8 3 255 (WSW) 181 clear none 22:01 32 8 1 250 (WSW) 164 clear none 23:01 32 8 0 247 (WSW) 150 clear none 00:01 33 7 2 264 (W) 218 clear none 01:01 33 4 0 271 (W) 209 clear none 02:01 33 2 3 265 (W) 167 clear none 03:01 34 -10 2 202 (SSW) 231 clear none 04:01 36 -9 7 198 (SSW) 252 clear none 05:01 36 -8 5 261 (W) 261 clear none 06:01 35 -10 1 240 (WSW) 269 clear none Note: the wind was coming from the azimuth listed.
