APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday January 25, 2010 (MJD 55222) ---=== OBSERVING TEAM ===--- Alaina Shelden Kaike Pan Steph Snedden (afternoon) ---=== OBSERVING PLAN ===--- MARVELS and BOSS sciences ---=== OBSERVING SUMMARY ===---= 5 hours are lost to belowing snow. When open,we observed: Marvels: plate 3634A, 3714B, 3715A. BOSS plate, 3779. DONE Possible broken fiber: cart 1, A side: 107/108 cart 9, B side, 57/58, 75/76. MARVELS team asked to adjust A/C setting in MARVELS room to 21 C, it is currently set at 18 C. ---=== OBSERVING LOG ===--- Afternoon: ---------- MARVELS CCD is still in the process of cooling down. At 4:30Z, it was at -40 C. Telescope and systems checked out. No problem to report. 4:40Z started ventilation. 4:45Z marvles lamps on. Cartridge 1, the first cartridge for tonight was mounted. Night: ------- 01:00Z enclosure off. Marvels CCD temperature at -80 C. 01:30Z cart 1, plate 3634A, field 1110. After goto starting th guider, it took one image, then quit. Alaina restarted the guider from the stageManager. SOGTF. 01:30Z marvels pre-calibs.

Clear sky with bad seeing (2-3"). During the exposure, the rain sensor went off a few time. We did physical on site check, the blowing snow is not that bad, when gust wind came, we could see a few drift snow through flashlight, so we decided to let the exposure finish. We also noticed that marvels CCD house temperature was out of spec, Alaina sent Marvels team an email on this.

Keep ventiliation on. 07:30Z Wind speed were down to 20 mph during last half hour, and physical on site check did not see belowing snow, we decided to re-open. 07:50Z Marvels calibs.

Took a while to find guiding stars. After finding the stars, the offsets are: ObjArcOff = -0.003516, 0.000000, 4771215513.94000, 0.003309, 0.000000, 4771215513.9400 GuideOff = 0.000000, 0.000000, 4771215514.36000, 0.000000, 0.000000, 47 71215514.36000, 0.018697, 0.000000, 4771 09:35Z started a 50 min science exposure. The sky was mostly clear. Seeing was about 1.7". T09:34:03.760.fits STAR 26.190332 864.14990 All fibers have signals.

Hartmann tests suggested to move b2 focus ring by -19 degree. But we were not able to move the ring because the outring is too tight. 11:10Z started science exposure. Partly cloudy sky with 1.4" seeing. We got six 15-min exposures on the plate and declared done. 13:20Z endNight finished. ---=== IMAGING RUN SUMMARY ===--- ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- ---=== LTMATCH RESULTS ===--- ---=== SPECTROSCOPY DATA SUMMARY ===--- ---=== TELESCOPE OFFSETS AND SCALE I ===--- ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- ---=== WEATHER LOG ===--- 00:21Z 33 6 10 321 (NW) 78 - 00:55Z 31 4 8 356 (NNW) 78 - 01:26Z 30 -3 14 354 (NNW) 83 - 01:56Z 30 5 14 14 (NNE) 115 - 02:29Z 29 6 8 348 (NNW) 118 - 03:03Z 31 8 18 9 (N) 157 - 03:37Z 31 9 22 21 (NNE) 79 - 04:07Z 31 11 15 22 (NNE) 81 - 04:41Z 34 17 9 11 (N) 38 - 05:15Z 34 18 8 45 (NE) 52 - 05:45Z 33 18 6 359 (NNW) 17 - 06:16Z 33 18 7 8 (N) 47 - 06:46Z 33 18 10 346 (NNW) 20 - 07:20Z 31 20 12 344 (NNW) 59 - 07:54Z 32 20 12 343 (NNW) 51 - 08:24Z 33 19 13 329 (NNW) 64 - 08:54Z 33 19 7 357 (NNW) 51 - 09:29Z 34 20 13 334 (NNW) 42 - 09:59Z 34 19 13 312 (NW) 46 - 10:32Z 34 17 12 305 (NW) 72 - 11:06Z 34 18 8 287 (WNW) 66 - 11:40Z 34 19 5 268 (W) 63 - 12:11Z 34 19 3 271 (W) 59 - 12:44Z 33 19 6 262 (W) 43 - 13:14Z 33 19 6 253 (WSW) 46 - ---=== TELESCOPE STATUS ===--- ---=== SOFTWARE USED ===--- ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A -0.7040 -0.6940 Axial B -0.0260 -0.0410 Axial C -0.3790 -0.3710 Trans D 11.6100 11.6170 Lateral E 10.3759 10.3505 Lateral F 11.9507 11.9253 GALILS Commanded: 9900. 400. 5850. 1200. 2950. 2750.
