The first-half observer had some trouble with slow image downloads, but from a traceroute it looked as if the slowest portion was probably her ISP. So she might observe from campus in the future. Download speeds improved somewhat later in the evening, but I kept running the guider for her to minimize bandwidth. DIS red and half of DIS blue worked well for the desired science. The blue end of the blue spectrum is still affected by contamination. We had some thin clouds rolling in around midnight but they mostly cleared by 5am. The very exciting news is THE TERTIARY IS FIXED!!!!! So it was very easy to move to NM01! Thank you everyone who worked so hard to make this happen! No problems tonight. ------- 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 -------------------------------------------------------------------------- 19:05 dcamera 454( 1730) -99 62 20.5 23.3 22.6 22.9 21.8 - 1.06 00:33 kosmos 564( 1743) -121 69 18.2 17.7 18.5 17.6 17.7 - 1.39 03:07 ecamera 372( 483) 67 45 17.4 17.0 17.6 16.8 16.9 ND3 1.62 04:58 ecamera 331( 460) 82 18 16.4 16.9 17.6 16.8 17.0 1.00 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 74 31 8 276 (W) 518 clear none 17:00 73 30 8 325 (NW) 507 clear none 18:00 75 34 6 261 (W) 523 clear none 19:00 71 33 6 262 (W) 607 clear none 20:00 69 34 2 217 (SW) 838 clear none 21:00 69 34 5 199 (SSW) 680 clear none 22:00 68 34 6 219 (SW) 655 clear none 23:00 66 32 8 185 (S) 562 clear none 00:00 65 33 7 168 (SSE) 665 mstly clr none 01:00 64 35 10 157 (SSE) 954 clear none 02:00 64 36 8 171 (S) 1167 mstly clr none 03:00 66 35 11 186 (S) 1027 mstly clr none 04:00 62 36 12 167 (SSE) 1254 mstly clr none 05:00 62 37 11 179 (S) 1245 mstly clr none 06:00 61 43 13 193 (SSW) 1441 clear none Note: the wind was coming from the azimuth listed.
