APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday March 25, 2008 (MJD 54551) ---=== OBSERVING TEAM ===--- Dan Oravetz (observer) Elena Malanushenko (observer) Dmitry Bizyaev (dayshift) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We finished one plate 2253, cart 4. We think that we finished cart 6 plate 2394 and we requested BY to check it (total observation time is 2h 20 min) Obtained useful signal on plates 2958 (cart 9), 2893 (cart 3), and 1670 (cart 8). We have photometric conditions and low humidity 15-20%. But the dust was little high and we obtained about 30K dust-hours. Please, check the mirror. ---=== OBSERVING LOG ===--- Afternoon: ---------- ntp_check OK iccSoundOff OK Bias on col 3 "r" of the imager looks non-uniform, t-bars switched, bias taken with then unlatched (looks very good), then switched off, and then bias with t-bars latched became good. This kind of problems is known and appear sometimes. Collimation checked. 00:14Z began ventilation. Night: ------ 01:30Z enclosure is off Cart 9, plate 2958, baoTest Used FK5 to find Guider Stars T = 9C, focLoop has foc=0, seeing 1.3" 02:11 preCal - out of Spec --> Moved pistons on +2000 02:26 preCalib - ok 02:34 science 1500 sec exposure 03:02 science 1500 sec exposure 03:30 science 1500 03:58 science 1500 --> 1800 04:31 postCal (s/n)^2 = 20.9. This plate needs r1,r2>30, so we need to continue the observations.

We think this plate is done and ask BY to check it. Cart 3 plate 2893 segue Used FK5 to find the guider stars 08:51 preCalib 08:58 science 1500 09:26 science 1500 09:54 postal This plate is expired and we observed it 20 min behind of that time. Cart 4 plate 2253, segue Used FK5 to find Guider Stars 10:23 science 1500 10:52 science 1500 - aborted as the SOS show a signal which is enough to declare this plate "DONE" Cart 8 plate 1670, old chunk We used FK5 and spiral pattern to find guider stars. The offset was some A=-15, D=+5. 11:23 science 1500 11:36 Twilight endNight is completed. 12:05 enclosure is on. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7396 22:27Z 22:51Z 100 O -130.37 -124.33 54 ignore 7397 22:56Z 23:06Z 100 O -122.99 -120.61 30 ignore 7398 23:12Z 23:32Z 100 O -119.08 -113.95 48 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 51224, plate -9999 ------- 22:30 51224 0.0 bias ----- sequence 51225, plate 2394 ------- 23:04 51225 10.0 flat 23:06 51226 2.0 arc 23:19 51227 3.0 arc 23:22 51228 3.0 arc ----- sequence 51229, plate -9999 ------- 00:45Z 51229 0.0 bias {{}} ----- sequence 51230, plate 2394 ------- 00:53Z 51230 0.0 bias {{}} ----- sequence 51231, plate 2958 ------- 02:14 51231 10.0 flat 02:16 51232 2.0 arc 02:29 51233 10.0 flat 02:31 51234 2.0 arc 03:02 51235 1500.0 target 03:29 51236 1500.0 target 03:57 51237 1501.0 target 04:30 51238 1801.0 target 04:34 51239 10.0 flat 04:36 51240 2.0 arc ----- sequence 51241, plate 2394 ------- 04:57 51241 10.0 flat 05:00 51242 2.0 arc 05:30 51243 1500.0 target 05:57 51244 1501.0 target 06:25 51245 1500.0 target 06:29 51246 10.0 flat 06:31 51247 2.0 arc 07:01 51248 1500.0 target 07:29 51249 1500.0 target 07:57 51250 1501.0 target 08:02 51251 10.0 flat 08:04 51252 2.0 arc 08:35 51253 1501.0 target ----- sequence 51254, plate 2893 ------- 08:54 51254 10.0 flat 08:56 51255 2.0 arc 09:25 51256 1501.0 target 09:53 51257 1500.0 target 09:56 51258 10.0 flat 09:59 51259 2.0 arc ----- sequence 51260, plate 2253 ------- 10:18 51260 10.0 flat 10:20 51261 2.0 arc 10:50 51262 1500.0 target ----- sequence 51263, plate 1670 ------- 11:18 51263 10.0 flat 11:20 51264 2.0 arc 11:50 51265 1500.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:43Z 9 2958 96.96 0.0023 63.92 0.0061 260.04 0.0206 1.000150 05:14Z 6 2394 165.83 0.0052 62.46 0.0034 -23.54 -0.0002 1.000210 09:55Z 3 2893 276.11 0.0009 47.85 0.0026 117.20 0.0240 1.000200 10:58Z 4 2253 96.76 0.0019 73.08 0.0049 -94.39 0.0209 1.000000 11:24Z 8 1670 227.91 0.0013 55.71 0.0010 75.55 0.0111 1.000200 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:43Z 9 2958 1.00015 -1481 -83 0 97 64.0 8.7 14 260 -- 1.3" 05:13Z 6 2394 1.00021 -2074 -595 -25 166 62.4 8.9 16 271 -- 1.2" 09:55Z 3 2893 1.00020 -1975 -422 25 276 47.8 6.6 16 278 -- 1.3" 10:58Z 4 2253 1.00000 0 1177 50 97 73.1 6.8 20 288 -- 1.3" 11:23Z 8 1670 1.00020 -1975 -422 50 228 55.8 6.3 20 280 -- 1.4" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:31Z 53 14 9 265 (W) 2178 - 22:01Z 55 16 14 238 (WSW) 2158 - 22:33Z 55 14 16 261 (W) 2227 - 23:07Z 58 13 21 267 (W) 2190 - 23:37Z 56 10 16 253 (WSW) 2361 - 00:08Z 54 9 23 264 (W) 2749 - 01:08Z 50 3 17 271 (W) 2527 - 01:38Z 49 1 14 256 (WSW) 2091 - 02:08Z 48 0 21 255 (WSW) 2075 - 02:39Z 48 0 16 262 (W) 2379 - 03:11Z 47 1 14 268 (W) 2048 - 03:41Z 48 0 17 254 (WSW) 2120 - 04:11Z 48 0 17 258 (WSW) 2183 - 04:41Z 48 0 12 257 (WSW) 2339 - 05:12Z 47 0 16 273 (W) 2482 - 05:43Z 47 0 13 267 (W) 2620 - 06:14Z 47 1 14 269 (W) 2587 - 06:44Z 47 0 10 265 (W) 2652 - 07:14Z 46 1 15 267 (W) 2727 - 07:46Z 46 2 12 266 (W) 2733 - 08:17Z 45 1 16 264 (W) 2806 - 08:48Z 45 2 18 270 (W) 2874 - 09:19Z 44 1 15 269 (W) 2892 - 09:49Z 43 1 16 269 (W) 3004 - 10:19Z 43 1 16 290 (WNW) 3143 - 10:49Z 43 2 13 266 (W) 3348 - 11:19Z 43 2 20 285 (WNW) 3345 - 11:49Z 43 2 20 286 (WNW) 3200 - 12:20Z 42 1 20 271 (W) 3429 - ---=== TELESCOPE STATUS ===--- 00:14Z - Began ventilation.
