Spectro focus set for 0C (sp1) and -1C (sp2). 23:00Z - Began ventilation. Swapped imager dewar. 23:59Z - Stopped ventilation because of critical humidity. Attached LN2 autofill lines. Night: ----- 00:55Z - Humidity dropped back to acceptable levels. Enclosure off, louvers opened, fans on. Topped-off spectro dewars.

Some yellow values again, but getting better as temps. drop. 02:11Z - Science. 1500s. 02:35Z - Low-laying clouds began moving through at the conclusion of the exposure. 02:39Z - postCalibs.

Cart. 5, 3185, Nov08c_SEGUE2 **************************** 02:49Z - gotoField. We didn't see guide stars, but when we went to a fk5, it was plainly in fiber 10, so we weren't too far offset. Adjusted scale and did a focus sweep. We still had some semi-transparent clouds moving quickly overhead that didn't show up on the IR satellite picture. 03:01Z - preCalibs. 03:07Z - Science. 1800s. Efficiency 45% at the start due to clouds. 03:36Z - endStare. The clouds were growing thicker and the efficiency was correspondingly decreasing (4% at this point) with no sign of improvement during the rest of the exposure, so we ended the exposure, closed the flat-field petals and monitored the clouds. This exposure was declared bad. 04:14Z - The efficiency was almost 60% so we decided to try again. 04:15Z - Science. 1800s. 04:48Z - preCalibs. 04:54Z - Science. 1500s. 05:22Z - postCalibs.

We had lost guide stars for a few minutes and the cloud camera didn't show a break in the clouds. 11:55Z - Clouds have persisted the rest of the night and we were unable to see guide stars on repeated attempts over the last few hours. Conditions did not look as if they were going to improve. We called it. 12:00Z - Enclosure on, fans off, louvers closed, LN2 autofill lines connected. 12:05Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7870 22:20Z 22:37Z 100 O 138.02 142.15 39 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 57504, plate 3105 ------- 22:31 57504 10.0 flat 22:33 57505 2.0 arc 22:36 57506 3.0 arc 22:39 57507 3.0 arc 01:28 57508 10.0 flat 01:31 57509 2.0 arc 02:04 57510 1800.0 target 02:08 57511 10.0 flat 02:10 57512 2.0 arc 02:39 57513 1500.0 target 02:41 57514 10.0 flat 02:44 57515 2.0 arc ----- sequence 57516, plate 3185 ------- 03:04 57516 10.0 flat 03:06 57517 2.0 arc 03:37 57518 1657.0 target 04:48 57519 1800.0 target 04:51 57520 10.0 flat 04:53 57521 2.0 arc 05:22 57522 1501.0 target 05:25 57523 10.0 flat 05:27 57524 2.0 arc ----- sequence 57525, plate 3175 ------- 05:52 57525 10.0 flat 05:55 57526 2.0 arc 06:28 57527 1801.0 target 07:01 57528 1800.0 target 07:04 57529 10.0 flat 07:07 57530 2.0 arc 07:40 57531 1800.0 target 08:02 57532 1144.0 target 08:08 57533 10.0 flat 08:11 57534 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:32Z 2 3105 -4.41 0.0015 47.23 -0.0002 176.24 0.0327 0.999850 03:07Z 5 3185 17.93 0.0029 48.25 -0.0015 195.14 0.0104 0.999920 05:15Z 5 3185 -28.85 0.0029 45.60 -0.0015 155.85 0.0104 0.999880 05:58Z 3 3175 126.08 0.0017 48.56 -0.0052 -88.91 0.0238 1.000020 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:32Z 2 3105 0.99985 1480 2716 300 -4 47.2 0.1 18 232 gdr. 1.6" 03:07Z 5 3185 0.99992 789 1991 150 18 48.2 1.2 11 260 gdr. 1.4" 05:14Z 5 3185 0.99988 1184 2216 40 -29 45.6 2.1 19 228 gdr. 1.7" 05:58Z 3 3175 1.00002 -196 1062 40 126 48.5 2.4 24 222 gdr. 1.6" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:29Z 33 26 15 224 (SW) 902 - partly cloudy 23:01Z 33 26 17 214 (SW) 1029 - partly cloudy 23:33Z 32 27 12 224 (SW) 933 - partly cloudy 00:05Z 30 27 16 203 (SSW) 968 - clear 00:37Z 30 25 15 202 (SSW) 890 - clear 01:09Z 32 22 22 238 (WSW) 588 - clear 01:40Z 32 24 11 230 (SW) 723 - clear 02:11Z 32 25 15 258 (WSW) 706 - mostly clear 02:42Z 33 26 19 223 (SW) 845 - partly cloudy 03:14Z 34 26 23 239 (WSW) 760 - partly cloudy 03:46Z 35 25 18 255 (WSW) 762 - partly cloudy 04:18Z 35 26 20 212 (SSW) 693 - partly cloudy 04:49Z 36 26 20 229 (SW) 618 - mostly clear 05:19Z 36 27 19 226 (SW) 645 - clear 05:51Z 36 27 19 240 (WSW) 636 - clear 06:23Z 35 28 20 248 (WSW) 629 - clear 06:53Z 35 28 14 244 (WSW) 621 - clear 07:24Z 36 27 25 211 (SSW) 581 - partly cloudy 07:55Z 36 26 22 219 (SW) 507 - partly cloudy 08:27Z 37 25 21 209 (SSW) 509 - mostly cloudy 09:00Z 36 26 23 221 (SW) 494 - clouds 09:32Z 36 26 21 223 (SW) 621 - clouds 10:04Z 35 26 20 202 (SSW) 629 - clouds 10:36Z 35 27 17 200 (SSW) 767 - clouds 11:08Z 35 27 23 215 (SW) 757 - clouds 11:40Z 34 27 19 213 (SSW) 751 - clouds ---=== TELESCOPE STATUS ===--- 23:00Z - Began ventilation.
