Hmmmm...) The telescopes (both of them!) and instruments (all of them!) worked well, but the second-half observer had considerable trouble with TUI, on the same machine she had been using for years. Messages did not get through, boxes apparently checked or unchecked themselves, and a series of darks were taken instead of the intended sky exposures. By the end I was observing for her and communicating through phone texts. So she may need some help troubleshooting this problem before her next observations in August. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- SU01 R I/S 04:15 05:00 mysterious TUI trouble ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:39 ecamera 564( 308) 43 77 17.2 19.2 19.5 18.5 17.5 ND2 0.90 23:49 tcamera 391( 1287) 221 55 15.9 15.8 16.6 15.5 15.6 Ks 1.02 01:21 arctic 473( 1146) 11 37 14.7 15.0 15.7 14.7 14.8 JC-R 1.38 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 76 32 10 183 (S) 660 clear none 17:00 71 30 4 223 (SW) 688 clear none 18:00 70 28 8 200 (SSW) 991 clear none 19:00 69 27 13 207 (SSW) 690 clear none 20:00 65 24 10 156 (SSE) 725 clear none 21:00 63 22 14 169 (S) 672 clear none 22:00 62 19 16 145 (SE) 630 clear none 23:00 61 20 12 147 (SSE) 611 clear none 00:00 61 22 14 151 (SSE) 671 clear none 01:00 59 26 15 136 (SE) 948 clear none 02:00 59 27 9 118 (ESE) 847 clear none 03:00 58 31 11 126 (SE) 799 clear none 04:00 57 30 9 148 (SSE) 760 clear none 05:00 59 32 10 182 (S) 795 clear none 06:00 56 32 7 185 (S) 805 clear none Note: the wind was coming from the azimuth listed.
