APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday October 1, 2005 (MJD 53645) ---=== OBSERVING TEAM ===--- Night: Mike Harvanek Kaike Pan Support: Connie Rockosi (phone) Steph Snedden (phone) Jim Gunn (phone) ---=== OBSERVING PLAN ===--- Supernova science. ---=== OBSERVING SUMMARY ===--- We imaged 82 S from lambda +114.5 to +134.5 (ramps included). Most of the night was lost to clouds. i5 is still misbehaving. Jim changed the voltages for this chip back to their original settings after determining that the work done on it the previous night had not improved the performance. Remember to use setup iop -t to get the sop version with the reduced requirement for available disk space. The mcptpm log files can be found at /home/data/mcptpm on sdsshost2. ---=== OBSERVING LOG ===--- Afternoon: ---------- i5 was misbehaving. We called Connie. She told us she had worked on it last night and that we should watch for "low" areas to the right of bright objects. She also told us to call Jim if we got on the sky so that he could take a look at it. sop was blowing up on the pad because of lack of disk space. This was due to the fact that we were running current iop not test iop. So, remember to use setup iop -t until further notice. We could not find the mcptpm log files (to check that the tpm is logging). They are now located at /home/data/mcptpm on sdsshost2. Thanks Steph! Night: ------ We opened doors and started ventilating at 00:45Z. However, it was heavily overcast at sunset so we did not remove the enclosure. The skies started to clear but the satellite showed a large mass of clouds moving up from Mexico, suggesting this was only a brief sucker hole. We kept the enclosure on. However, the cloud camera remained fairly clear and the satellite showed the large mass of clouds to be breaking up just as it arrived. So we removed the enclosure around 03:30Z while keeping a cautious eye on the clouds. Around this time, Ben from Chicago called and then Rick Kessler called. Both informed us that SN05 had gone down. We rebooted the machine per Rick's instructions. Fritz called shortly thereafter and we had to push its button again. Apparently, this solved the problem. We finally got on the sky around 04:00Z. We called Jim Gunn so that he could monitor i5. From what we saw on the scrolling display, there appeared to be blue (dark) channels to the right of bright objects. We do not know if this is better, worse or the same as last night, however. After the run (5675 - see below) ended, Jim called back and said that the voltage changes that Connie had done last night did not appear to improve i5's performance. He had changed the voltages back to their original settings at frame 67 and then examined 20 frames before and 20 frames after the change. He could not see much difference before and after the change. He left the i5 voltages at their original settings because he believed these were safer. Note that this voltage change caused 2 voltage errors (vrd2 and vdd2) for ccd 25 (i5) at 04:38Z that were reported by the watcher. Also note that this voltage change caused a discontinuity in the background of frame 67 of run 5675 and there might be problems processing this. 04:00Z. Run 5675. 82 S, start lambda +114. Pointing and seeing good from the beginning. In focus at frame 23, lambda 116.8. Seeing good throughout. The clouds started to get thick towards the end but we called the run good through the end (frame 141, lambda +134.5). We ended the drift around 05:21Z due to increasing clouds and put the enclosure on about 05:30Z. Note that there is a discontinuity in the background of frame 67 on i5 (ccd 25) and this may cause problems when processing. (See the previous paragraph for more details.) Kaike's iop/tcc timed out when he issued the first scanStripe command for run 5675. This happened around 03:55:31Z. We waited for the iop prompt to return, did a tccClose followed by a startDa -tcc, reissued the scanStripe command and all was well. After putting the enclosure on we did an on-telescope bias (run 5676). Everything looked good except for i5 which we know is misbehaving. It appeared that SoS stopped copying over data. Frames 34102 - 34104 were on sdsshost2 but not on SoS. The sos_status command said SoS was running. However, we issued an sos_stop, killed the processes that were still running and then issued an sos_start. After that, the missing data started appearing on SoS and all was well. The rain sensor went off around 09:15Z. We closed the doors the remainder of the way (they were only half open), shut off fans and closed louvers. We never reopened. endNight rejoiced and the supernova spooling appeared to be successful although we could not logout of sn10 after we started the spooling. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5674 23:29Z 23:54Z 100 O 72.34 78.51 54 ignore 5675 04:01Z 05:21Z 82 S 114.40 134.59 149 science good 5676 05:47Z 06:15Z 100 O 166.97 174.06 62 bias on-telescope ---=== IMAGING RUN DETAILS ===--- See the main log. ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 5675 18 4 40 -4.000 0.167 -3.100 0.152 -0.00605 222 49 5675 70 4 102 -4.300 0.152 -3.300 0.146 -0.00674 222 49 5675 123 4 107 -4.200 0.175 -3.200 0.109 -0.00682 222 49 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 5675 28 1 49 318 69 -1.036 0.187 0.296 0.187 -0.00100 5675 28 1 49 318 66 -0.702 0.311 0.572 0.165 -0.00192 5675 28 1 49 318 70 -0.412 0.349 0.682 0.159 -0.00229 5675 28 1 49 318 66 0.058 0.240 0.846 0.182 -0.00284 5675 28 1 49 318 76 0.191 0.132 0.924 0.218 -0.00311 5675 46 1 49 318 70 -0.664 0.204 0.669 0.383 -0.00225 5675 46 1 49 318 72 -0.511 0.278 1.050 0.314 -0.00353 5675 46 1 49 318 77 -0.031 0.237 1.342 0.277 -0.00451 5675 46 1 49 318 80 0.365 0.155 1.534 0.192 -0.00516 5675 46 1 49 318 74 0.781 0.167 1.517 0.157 -0.00510 5675 80 1 49 318 74 -0.503 0.329 0.450 0.129 -0.00151 5675 80 1 49 318 72 -0.015 0.184 0.698 0.193 -0.00235 5675 80 1 49 318 71 0.282 0.141 0.687 0.253 -0.00231 5675 80 1 49 318 76 0.334 0.207 1.033 0.206 -0.00347 5675 80 1 49 318 73 0.861 0.214 1.194 0.253 -0.00401 5675 99 1 49 318 36 -0.382 0.251 0.534 0.138 -0.00179 5675 99 1 49 318 55 -0.029 0.216 0.701 0.205 -0.00236 5675 99 1 49 318 66 0.436 0.214 0.852 0.214 -0.00287 5675 99 1 49 318 46 0.502 0.185 1.063 0.194 -0.00358 5675 99 1 49 318 53 0.812 0.283 1.330 0.210 -0.00447 5675 130 1 49 318 22 -0.462 0.147 0.252 0.219 -0.00085 5675 130 1 49 318 23 -0.187 0.219 0.662 0.144 -0.00223 5675 130 1 49 318 11 0.133 0.110 0.881 0.171 -0.00296 5675 130 1 49 318 11 0.270 0.221 1.095 0.152 -0.00368 5675 130 1 49 318 10 0.911 0.176 0.920 0.144 -0.00309 ---=== 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 34099, plate -9999 ------- 23:38Z 34099 0.0 bias 23:44Z 34100 0.0 bias 23:49Z 34101 0.0 bias 02:48Z 34102 0.0 bias 07:10Z 34103 0.0 bias ----- sequence 34104, plate 0 ------- 07:17Z 34104 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:29Z imager -41.93 0.0000 49.03 0.0000 55.58 0.0000 1.000000 ---=== 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 ------------------------------------------------------------------------------ 04:29Z imager 1.00000 0 -408 -327 -42 49.0 13.3 11 210 i-23 1.0" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:50Z 59 28 9 253 (WSW) -9999 - 00:22Z 57 30 8 246 (WSW) -9999 - 00:54Z 57 27 10 216 (SW) -9999 - mostly cloudy 01:26Z 57 27 7 196 (SSW) -9999 - mostly cloudy 01:58Z 56 23 10 238 (WSW) -9999 - clearing 02:30Z 57 19 11 234 (SW) -9999 - partly cloudy 03:03Z 54 20 11 226 (SW) -9999 - mostly clear 03:35Z 55 21 11 216 (SW) -9999 - mostly clear 04:05Z 55 21 11 237 (WSW) -9999 - partly cloudy 04:36Z 55 22 12 228 (SW) -9999 - mostly cloudy 05:06Z 55 21 10 229 (SW) -9999 - mostly cloudy 05:39Z 56 21 11 219 (SW) -9999 - mostly cloudy 06:16Z 56 23 13 212 (SSW) -9999 - mostly cloudy 06:48Z 56 25 16 220 (SW) -9999 - mostly cloudy 07:20Z 55 31 17 205 (SSW) -9999 - mostly cloudy 07:52Z 55 32 14 213 (SSW) -9999 - mostly cloudy 08:24Z 54 32 13 243 (WSW) -9999 - mostly cloudy 08:56Z 55 31 11 237 (WSW) -9999 - cloudy 09:29Z 55 31 12 267 (W) -9999 - cloudy, sprinkles 10:01Z 53 34 8 292 (WNW) -9999 - cloudy, sprinkles 10:33Z 54 33 7 329 (NNW) -9999 - cloudy, sprinkles 11:05Z 53 35 9 295 (WNW) -9999 - cloudy, sprinkles ---=== TELESCOPE STATUS ===--- 00:45Z Enclosure doors opened, fans and blowers on, louvers opened. 03:30Z Enclosure off. 05:30Z Enclosure on (clouds). 09:15Z Doors closed, fans and blowers off, louvers closed (rain).
