APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday October 3, 2008 (MJD 54743) ---=== OBSERVING TEAM ===--- Audrey Simmons Dmitry Bizyaev ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Running clouds all night long. Overcast in the morning. We roasted aluminium pancakes stuffed with fiberglass spaghetti fos SEGUEII in a starlight collected by 2.5m mirror. Skillet 1 dish 3129 is way undercooked, just sprinkled with rare obscured photons ; Skillet 9 dish 3132 is half done (underdone any way); Skilled 7 dish 3121 was seasoned with some colorful photons but this didn't add anything to the plate doneness. ---=== OBSERVING LOG ===--- Afternoon: ---------- ntp_check ok iccSoundOff ok imager bias ok spectro bias ok >apo_plotbias, 55222 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00055222.fit -6.0 -4.2 -2.7 2.1 7.3 8.4 10.5 sdR-b2-00055222.fit -8.6 -6.3 -4.9 1.1 7.2 9.0 10.9 sdR-r1-00055222.fit -7.3 -5.3 -3.5 1.7 6.7 8.4 10.6 sdR-r2-00055222.fit -8.2 -6.4 -5.1 0.9 6.5 8.3 10.7 All calib lamps are ok. Collimation with cart. 1: should be good for ~ 9C. 23:40Z ventilation started, doors and louvers opened, fans on. Night: ------ 01:14Z Enclosure off. Running clouds around the sky. 01:53Z gotoField with cart. 1 plate 3129 fk5 used precal 02:11Z science 1500 --> 1800 clouds, low effeciency during the exposure. b1 is below 2, so we declare this exposure as bad. 02:52Z science 1800 decent exposure 03:25Z midcal 03:31Z science 1800 bad again (clouds, low efficiency) --- 04:04Z cart.9. plate 3132 mounted GSOGTF precal 04:28Z science 1800 good exposure! 05:01Z science 1800 not bad 05:40Z science 1800 decent (r1 only is below 2.0, we don't count r1 for SegueII now 06:12Z science 1800 same as previous 06:45Z postcal. Actually, we are in rather dense clouds. Efficiency dropped to zero. We pause observations. 07:20Z attempt of resuming exposures; science 1800... no, declared as bad. 07:58Z science 1800 - this one is good; exposure was paused few times 08:35Z midcal 08:42Z science 1800 - ; exposure was paused few times 09:29Z postcal -- 09:38Z cart 7. plate 3121 mounted (this is a low priority plate today, but we have no choice and mount it to get additional signal). GSOGTF 09:49Z precal 09:55Z science 1500 --> 1800 paused many times because of clouds. Exposure is bad any way. The sky is overcast. We decided to close. 11:25Z enclosure on. 11:30Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7719 23:07Z 23:23Z 100 O 69.03 73.01 40 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 55215, plate -9999 ------- 23:10 55215 0.0 bias ----- sequence 55216, plate 3129 ------- 23:20 55216 10.0 flat 23:23 55217 2.0 arc 23:26 55218 3.0 arc 23:28 55219 3.0 arc 23:33 55220 10.0 flat 23:36 55221 2.0 arc ----- sequence 55222, plate -9999 ------- 00:01 55222 0.0 bias ----- sequence 55222, plate 3129 ------- 02:05 55223 10.0 flat 02:08 55224 2.0 arc 02:51 55225 1803.0 target 03:24 55226 1801.0 target 03:27 55227 10.0 flat 03:30 55228 2.0 arc 04:03 55229 1800.0 target ----- sequence 55230, plate 3132 ------- 04:22 55230 10.0 flat 04:25 55231 2.0 arc 05:00 55232 1801.0 target 05:33 55233 1800.0 target 05:35 55234 10.0 flat 05:38 55235 2.0 arc 06:11 55236 1800.0 target 06:44 55237 1801.0 target 06:47 55238 10.0 flat 06:50 55239 2.0 arc 07:57 55240 1803.0 target 08:34 55241 1802.0 target 08:37 55242 10.0 flat 08:40 55243 2.0 arc 09:28 55244 1805.0 target 09:31 55245 10.0 flat 09:33 55246 2.0 arc ----- sequence 55247, plate 3121 ------- 09:50 55247 10.0 flat 09:53 55248 2.0 arc 10:34 55249 1803.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:04Z 1 3129 71.38 0.0033 49.08 0.0015 234.96 0.0122 1.000180 04:28Z 9 3132 70.67 0.0012 52.32 0.0021 235.19 0.0211 1.000220 10:26Z 7 3121 -14.13 -0.0011 68.48 0.0017 167.91 0.0082 1.000260 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:04Z 1 3129 1.00018 -1776 -337 -50 71 49.1 12.1 11 190 -- 1.1" 04:28Z 9 3132 1.00022 -2171 -664 -40 71 52.3 11.4 10 240 -- 1.2" 10:26Z 7 3121 1.00026 -2566 -976 15 -14 68.5 10.0 10 268 -- 1.1" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:40Z 62 31 9 251 (WSW) 895 - 23:13Z 58 28 8 234 (SW) 871 - 23:45Z 57 27 10 241 (WSW) 890 - some clouds 00:21Z 54 28 4 248 (WSW) 849 - '' 00:53Z 54 27 5 186 (S) 948 - clouds 01:26Z 52 27 9 190 (S) 932 - '' 01:56Z 54 25 10 193 (SSW) 892 - '' 02:26Z 52 27 12 205 (SSW) 1122 - '' 02:57Z 53 28 12 205 (SSW) 1052 - '' 03:30Z 52 30 15 236 (SW) 1090 - '' 04:02Z 53 32 12 213 (SSW) 1180 - '' 04:34Z 52 32 11 236 (SW) 1270 - '' 05:06Z 52 32 11 219 (SW) 1273 - '' 05:39Z 52 31 11 236 (SW) 1252 - '' 06:11Z 52 32 11 239 (WSW) 1174 - '' 06:43Z 52 33 9 256 (WSW) 1215 - '' 07:15Z 52 34 11 230 (SW) 1308 - '' 07:47Z 51 35 15 240 (WSW) 1151 - '' 08:19Z 50 36 12 225 (SW) 1105 - '' 08:52Z 50 37 11 221 (SW) 1040 - '' 09:24Z 49 37 10 214 (SW) 960 - clear 09:54Z 49 36 8 256 (WSW) 870 - clouds 10:26Z 50 36 9 267 (W) 768 - '' 10:56Z 49 36 10 277 (W) 746 - '' 11:28Z 49 36 10 264 (W) 739 - '' ---=== TELESCOPE STATUS ===--- 23:40Z - Began ventilation.
