The telescope, however, was not interested in cooperating during B-half. gcam needed startNubs+init at checkout. When I engaged the stop button at changeover in order to swap instruments, the altitude axis controller spontaneously reset and it took about 15 minutes to get it back. Then I did the instrument change, and we got on sky for 20 minutes and were in the middle of an image when the telescope stopped (around 47, 70) due to a collision of the telescope with the dome. I cleared the collision, reinitialized the telescope, we tried slewing back to the field--and it immediately collided again. Even with Russet's help we were unable to fix the dome collision problem, and we gave up on observing, but Ben was able to get the dome moving again by resetting a breaker in the dome controller box! (See PR2112 for more details.) ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- NA01 NICFPS T/U 01:05 01:23 Spontaneous alt controller reset NA01 TSPEC T/H 01:56 06:30 Dome failure to move ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 18:26 NICFPS 413( 1301) -30 35 5.4 8.9 7.7 8.7 6.7 H2-2.12 0.92 19:13 NICFPS 273( 1078) -48 50 5.4 7.4 6.7 6.6 5.4 H2-2.12 0.66 19:51 NICFPS 232( 1008) -58 44 5.4 6.7 6.3 6.2 5.4 H2-2.12 0.78 20:46 NICFPS 265( 1004) -70 33 5.3 5.7 5.8 5.5 5.2 MK-Ks 0.84 20:55 NICFPS 294( 1028) -72 31 5.2 5.6 5.7 5.4 5.1 MK-H 1.06 22:57 NICFPS 293( 941) -162 58 4.4 4.1 4.8 3.9 3.8 H2-2.12 0.86 23:56 NICFPS 300( 922) -153 54 5.0 3.5 4.1 3.3 3.8 H2-2.12 0.88 01:43 tcamera 388( 738) 53 69 3.8 3.3 3.9 3.1 3.9 Ks 0.86 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 51 25 9 258 (WSW) 672 ptly cldy none 17:00 48 26 7 195 (SSW) 631 ptly cldy none 18:00 44 24 2 232 (SW) 655 clear none 19:00 42 24 1 225 (SW) 670 clear none 20:00 42 23 6 183 (S) 631 clear none 21:00 42 20 7 185 (S) 479 clear none 22:00 41 17 9 182 (S) 383 clear none 23:00 39 22 8 163 (SSE) 644 clear none 00:00 41 20 7 183 (S) 578 clear none 01:00 41 21 7 181 (S) 549 clear none 02:00 39 20 7 213 (SSW) 510 clear none 03:00 41 20 7 235 (SW) 560 clear none 04:00 39 21 6 229 (SW) 721 clear none 05:00 39 20 6 262 (W) 612 clear none 06:00 39 21 5 263 (W) 781 clear none Note: the wind was coming from the azimuth listed.
