APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday March 31, 2009 (MJD 54922) ---=== OBSERVING TEAM ===--- Steph Snedden (Observer) Howard Brewington (Observer) Alaina Sheldon (afternoon-checkout training) ---=== OBSERVING PLAN ===--- SEGUE Science! ---=== OBSERVING SUMMARY ===--- Clear skies and good seeing during the first part of the night; Orographic clouds and variable seeing for the second half. The integrated dust count last night was >30K; the mirrors probably need to be checked and/or cleaned. Thanks! We had an MCP problem during the afternoon checkout. Alaina came in during afternoon for a more practice with the afternoon checkout. Added signal to: Cart 04, plate 3335 Could be DONE; Connie was contacted. Cart 03, plate 3321 Cart 07, plate 3306 DONE Cart 06, plate 3295 Cart 05, plate 3298 Clouds We could not move the scope to stow this morning with TCC; see log. ---=== OBSERVING LOG ===--- Afternoon: ---------- 22:30Z Started the afternoon checkout with Alaina's help. 22:50Z The software work being done on site caused an MCP problem and a short delay in the afternoon checkout. Howevever, Jon and Craig were able to fix the problem quickly. Thanks! Check the Problems Section for the misc Watcher messages that resulted. 23:20Z Resumed checkout 23:40Z Spectro focus was checked but not adjusted. It's set for about 5-degree C, and the collimate numbers are posted in the Problem Section. Apo_plotbias is also posted in Problems Section. 23:50Z Checkout completed; df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 117G 19G 87% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 835G 37G 96% /data sdssfiles1p:/data1/data 1.5T 670G 723G 49% /files 23:55Z Doors/louvers opened, fans turned on.

An FK5 was used to find the field in bright twilight. We've previously completed four (good) 30-minute exposures and one (poor) 30-minute exposure on this plate. Tonight, we added four more (good) 30-minute exposures. The first and second exposures, done tonight, enjoyed an efficiency of ~70%; the third one decreased to about 60%; the last one decreased to ~55% efficiency. The starting alt of the first exposure was about 67-degrees; the alt as the last exposure finished was 40-degrees. We think this plate is done but would like Connie to confrim. An email was sent to her. 02:27 60210 10.0 flat 02:29 60211 2.0 arc 02:44 Twilight end 03:04 60212 1800.0 target 03:37 60213 1801.0 target 03:40 60214 10.0 flat 03:42 60215 2.0 arc 04:17 60216 1801.0 target 04:50 60217 1800.0 target 04:53 60218 10.0 flat 04:55 60219 2.0 arc 05:01Z Cart 03, plate 3321 (Feb09aSEGUE2).

When we entered the command, we could see the TCC try to move the scope, but then it issued a slew end. Yet, the scope did not move. We had to move it with the mcpMenu to the stow position. 11:33Z Morning twilight 11:36Z endNight finished and was happy; misc Watcher messages are posted in the Problems Section. 12:57Z Sunrise ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 60204, plate -9999 ------- 22:54 60204 0.0 bias ----- sequence 60205, plate 0 ------- 23:41 60205 10.0 flat 23:44 60206 2.0 arc 23:54 60207 3.0 arc 23:57 60208 3.0 arc ----- sequence 60209, plate -9999 ------- 00:23 60209 0.0 bias ----- sequence 60210, plate 3335 ------- 02:27 60210 10.0 flat 02:29 60211 2.0 arc 03:04 60212 1800.0 target 03:37 60213 1801.0 target 03:40 60214 10.0 flat 03:42 60215 2.0 arc 04:17 60216 1801.0 target 04:50 60217 1800.0 target 04:53 60218 10.0 flat 04:55 60219 2.0 arc ----- sequence 60220, plate 3321 ------- 05:12 60220 10.0 flat 05:15 60221 2.0 arc 05:50 60222 1800.0 target 06:24 60223 1800.0 target 06:26 60224 10.0 flat 06:29 60225 2.0 arc ----- sequence 60226, plate 3306 ------- 06:53 60226 10.0 flat 06:55 60227 2.0 arc 08:04 60228 1800.0 target 08:37 60229 1801.0 target 08:40 60230 10.0 flat 08:42 60231 2.0 arc ----- sequence 60232, plate 3295 ------- 08:55 60232 10.0 flat 08:57 60233 2.0 arc 09:32 60234 1800.0 target ----- sequence 60235, plate 3298 ------- 10:30 60235 10.0 flat 10:33 60236 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:33Z 4 3335 -50.77 0.0004 66.72 0.0019 137.21 0.0194 0.999880 05:18Z 3 3321 224.73 0.0040 73.02 0.0032 55.12 0.0219 1.000010 07:32Z 7 3306 -24.14 0.0018 54.77 0.0027 159.85 0.0042 0.999890 09:00Z 6 3295 188.31 0.0043 56.94 0.0019 16.81 0.0048 0.999910 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 00:28Z 4 0 1.00000 1 1257 0 121 30.1 4.9 9 262 02:32Z 4 3335 0.99988 1184 2293 175 -51 66.8 2.7 17 210 gdr 1.6 05:18Z 3 3321 1.00001 -98 1095 50 225 73.0 3.6 16 264 gdr 1.7 07:32Z 7 3306 0.99989 1085 2065 0 -24 54.8 2.6 13 232 gdr 2.3 09:00Z 6 3295 0.99991 888 1996 100 188 56.9 2.3 16 228 gdr 2.0 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:17Z 42 0 11 305 (NW) 751 - 22:48Z 39 -4 7 269 (W) 719 - 23:22Z 45 0 10 243 (WSW) 746 - 23:54Z 41 -2 6 259 (W) 710 - 00:26Z 42 -1 10 262 (W) 795 - 00:58Z 38 -3 14 217 (SW) 729 - 01:29Z 36 -3 16 207 (SSW) 783 - 01:59Z 36 -2 17 200 (SSW) 984 - 02:30Z 36 1 18 212 (SSW) 1799 - 03:02Z 37 2 18 211 (SSW) 2146 - 03:32Z 36 3 18 235 (SW) 2405 - 04:03Z 37 0 13 245 (WSW) 2210 - 04:33Z 37 2 18 242 (WSW) 2165 - 05:03Z 37 2 16 246 (WSW) 2244 - 05:36Z 38 5 14 229 (SW) 2242 - 06:08Z 37 4 9 238 (WSW) 2261 - 06:38Z 37 4 14 212 (SSW) 2319 - 07:08Z 37 4 14 231 (SW) 2331 - 07:40Z 36 4 9 218 (SW) 2477 - 08:10Z 36 4 14 228 (SW) 2347 - 08:41Z 36 4 13 253 (WSW) 2404 - 09:13Z 35 4 14 238 (WSW) 2565 - 09:43Z 35 4 14 251 (WSW) 2631 - 10:14Z 35 4 14 217 (SW) 2629 - 10:45Z 34 3 14 220 (SW) 2600 - 11:17Z 35 3 15 213 (SSW) 2659 - ---=== TELESCOPE STATUS ===--- 23:22Z Doors and louvers open, fans on. 00:15Z Enclosure off. 11:23Z Enclosure on, doors and louvers closed, fans off.
