APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday October 25, 2005 (MJD 53669) ---=== OBSERVING TEAM ===--- Howard Brewington (swing) Olena Malanushenko (swing helper) Mike Harvanek (night) John Barentine (night) Viktor Malanushenko (training) Rick Kessler (superSuperNovaPhoneSupport) ---=== OBSERVING PLAN ===--- SuperNova Science! ---=== OBSERVING SUMMARY ===--- Imaged the entirety of stripe 82 S tonight (115 < lambda < -126) and 34 degrees of stripe 82 N (-162 < lambda < -126) in mostly photometric conditions, interrupted by about one hour of clouds. ---=== OBSERVING LOG ===--- Afternoon checkout: ------------------- The afternoon checkout went well. We are running the current version of IOP (v4_6_0b). After the spectro bias, we noticed that the SOS web-page was not updating; however, it started working later in the evening. While doing an imager bias, we got a Watcher error, i.e., FTP connection is hung. See problems section for the entire message. We tried rebooting photo-one but the same error message returned. The observers reported this error message last night, and it seems to be harmless. We note the image bellows pressure today stands at 48psi. Night: ------ We mounted the imager at 00:15Z and took an on-telescope bias (Run 5775) in the dark enclosure as we waited for the end of twilight. Pulled the building at 00:40Z. 01:35Z Run 5776 (SN Stripe 82 S, startLambda=115). Seeing is KILLER with ~15 chips subarcsecond. Skippy was happy from the get-go, and all in focus by frame 20. Astroline complained around frames 25-30 about no good stars in dewar 2 because of a very bright star that drifted from one chip to the next. Seeing degraded toward lambda=160 (RA=346, Frame 300) and headed up toward 1.5" on average. Clouds started forming over us at 07:07Z, Frame 565. Clouds persisted but were not thick enough to cause us to worry until humidity rose later. Clouds thickened significantly at 07:50Z (Frame 635, lambda=-151, RA=34). Sky was clear and photometric again at 08:33Z (Frame 709, lambda=-140, RA=45). It stayed clear until about 09:08Z (Frame 768, lambda=-131, RA=54) with some puffs of clouds in the east. Humidity crossed the 3 degree split threshold and we worried about being suddenly inundated with fog; over the next several minutes we watched as the humidity crested at 82% and then started falling again. Photometric again through the end of this run. Science ended at RA=57 (Frame 791, lambda=-127), then we did a 2 degree ramp to end at RA=59 (Frame 802, lambda=-126, 09:29Z). With the moon up and photometricity in question, we could do neither SEGUE nor Legacy imaging. Spectrograph 2 is still out of commission, so we continued SN imaging as last night. 09:37Z Run 5777 (SN Stripe 82 N, startLambda=-161.5). Sky is photometric for the moment. We did a 2 degree ramp into science. Skippy is happy and we're in focus from the start. Science began at lambda=-160, RA=25, Frame 18. Photometric throughout this scan. Humidity rose during ths last half-hour of this scan and we feared having to end early. The split dropped to < 2.5 deg C just about the time we entered the ramp. Science ended at Frame 230, lambda=-128, RA=57 and then a 2 deg ramp began, though we agreed to end this early if humidity continued to climb. Ended the drift at Frame 245, lambda=-126, RA=59 at 11:58Z. Closed up for the night at 12:10Z. Surfaces out at the telescope were tacky but not dripping, so we think we caught the humidity just in the nick of time. We turned on the heaters just in case in hopes of drying things out a bit in the enclosure. endNight rejoiced. We did NOT spool the SN data per instructions from Rick Kessler. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5772 21:45Z 22:06Z 100 O 69.74 75.10 49 ignore 5773 22:24Z 23:01Z 100 O 79.62 89.03 77 ignore 5774 23:08Z 00:09Z 100 O 90.73 105.86 115 ignore 5776 01:34Z 09:30Z 82 S 115.02 -125.74 810 science 5777 09:37Z 11:59Z 82 N -161.48 -125.71 253 science ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 5776 42 4 59 0.900 0.147 -3.200 0.123 -0.00063 202 55 5776 92 4 95 1.400 0.139 -2.900 0.089 -0.00031 202 55 5776 146 4 92 2.100 0.138 -2.200 0.112 -0.00066 202 55 5776 195 4 43 2.000 0.148 -1.900 0.118 -0.00046 202 55 5776 199 4 71 2.100 0.145 -1.800 0.105 -0.00019 202 55 5776 248 4 65 2.100 0.128 -1.600 0.120 -0.00012 202 55 5776 299 4 39 2.200 0.166 -1.700 0.109 0.00018 202 55 5776 299 4 39 2.200 0.166 -1.700 0.109 0.00018 202 55 5776 350 4 43 2.100 0.197 -1.600 0.134 0.00060 202 55 5776 402 4 56 2.800 0.143 -1.400 0.112 -0.00072 202 55 5776 429 4 42 2.900 0.184 -1.900 0.168 0.00046 202 55 5776 453 4 48 3.300 0.136 -2.000 0.161 0.00021 202 55 5776 505 4 38 3.300 0.137 -2.600 0.131 -0.00007 202 55 5776 557 4 38 3.400 0.118 -2.800 0.105 -0.00070 202 55 5776 606 4 51 3.000 0.141 -3.200 0.128 0.00024 202 55 5776 658 4 55 3.400 0.124 -2.900 0.147 0.00036 202 55 5776 667 4 48 3.200 0.147 -2.900 0.171 0.00038 202 55 5776 710 4 36 3.500 0.185 -2.600 0.186 -0.00010 202 55 5776 754 4 56 3.100 0.154 -2.900 0.125 0.00013 202 55 5776 760 4 62 2.900 0.173 -2.900 0.108 -0.00041 202 55 5777 21 4 43 4.400 0.157 -4.700 0.144 -0.02059 245 33 5777 73 4 51 4.400 0.119 -4.900 0.130 -0.01997 245 33 5777 125 4 38 4.600 0.111 -4.900 0.132 -0.02018 245 33 5777 176 4 55 4.500 0.135 -5.100 0.127 -0.01982 245 33 5777 228 4 42 4.500 0.124 -5.300 0.143 -0.02032 245 33 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 5776 788 1 55 338 25 -1.047 0.246 -0.328 0.397 0.00110 5776 788 1 55 338 25 -0.750 0.233 -0.265 0.271 0.00089 5776 788 1 55 338 19 -0.140 0.099 -0.039 0.374 0.00013 5776 788 1 55 338 18 -0.019 0.149 0.098 0.480 -0.00033 5776 788 1 55 338 16 0.063 0.223 0.093 0.432 -0.00031 ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): y QA Procedures Done (y/n): n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 34290, plate -9999 ------- 22:05 34290 0.0 bias 22:28 34291 0.0 bias 23:23 34292 0.0 bias 00:33 34293 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 23:09Z 5 0 1.00000 0 1257 0 121 30.0 11.2 6 255 -- 0.9 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:04Z 53 25 8 262 (W) -9999 - Clear 22:36Z 48 20 3 265 (W) -9999 - Clear 23:07Z 53 21 8 263 (W) -9999 - Clear 23:38Z 50 25 3 239 (WSW) -9999 - Clear 00:09Z 47 24 5 264 (W) -9999 - Clear 00:41Z 43 24 5 255 (WSW) -9999 - Clear 01:21Z 42 25 5 249 (WSW) -9999 - Clear 01:51Z 41 27 7 215 (SW) -9999 - Clear 02:23Z 42 27 6 187 (S) -9999 - Clear 02:53Z 44 24 7 182 (S) -9999 - Clear 03:25Z 42 25 4 190 (S) -9999 - Clear 03:57Z 43 26 6 190 (S) -9999 - Clear 04:30Z 42 25 7 209 (SSW) -9999 - Clear 05:00Z 42 26 9 220 (SW) -9999 - Clear 05:32Z 44 24 14 261 (W) -9999 - Clear 06:02Z 45 24 7 268 (W) -9999 - Clear 06:33Z 45 24 11 270 (W) -9999 - Clear 07:05Z 44 27 11 274 (W) -9999 - Clear 07:39Z 42 31 12 235 (SW) -9999 - Clear 08:09Z 42 32 9 238 (WSW) -9999 - PtlyCldy 08:42Z 44 30 7 257 (WSW) -9999 - PtlyCldy 09:13Z 41 35 10 213 (SSW) -9999 - PtlyCldy 09:43Z 41 36 12 215 (SW) -9999 - MstlyClr 10:14Z 41 34 15 238 (WSW) -9999 - MstlyClr 10:45Z 41 35 12 235 (SW) -9999 - Clear 11:16Z 41 35 10 236 (SW) -9999 - Clear 11:47Z 40 36 11 239 (WSW) -9999 - Clear 12:20Z 40 35 10 262 (W) -9999 - Clear ---=== TELESCOPE STATUS ===--- 23:40Z Opened doors and louvers, turned on fans 00:40Z Enclosure off 12:10Z Enclosure on, doors and louvers closed, fans off (and not a moment too soon!)
