APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 4, 2006 (MJD 53860) ---=== OBSERVING TEAM ===--- Kaike Pan ET crew: Jian Ge, Scott Fleming Visitor: Mike Harvanek ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- Observed four ET plates: E8024, 8026, 8022 and 8029. imager dewar needs to be swapped soon. Problems: 1) The shutter pressure on SDSS pneumatics panel in lower encloure is reading 78, slightly lower than its nomial value, 80. 2) lights in 1-m dome frequently flashed with opened louvers. an email message was sent to Jon Holtzman. 3). During the exposure of last plate, telescope stopped tracking with Altitude "AB" and rotator "AO" on. (see log). ---=== OBSERVING LOG ===--- Afternoon: --------- The shutter pressure on SDSS pneumatics panel in lower encloure is about 78, slightly lower than its nomial value, 80. Night: ------ Because ET calibrations need dark enclosure, we did not open till 03:15Z. 03:15Z enclosure off. 03:50Z cart 8, plate E8024. Stars on GTF. 05:50Z cart 4, plt E8026. Educated guess got stars which were offset by -9 in A. 08:30Z cart 7, plt E8022. on guiding star was on the edge of the fiber. We had a little trouble in swapping cartridge from #4 to #7. I cloud not push the Lindy cart in with cart 7 loaded on it. It appearded the cartridge was too high. I decided to unload the cart 7 to back spot of the lindy cart and unmounted cart 4 to the front spot, then put the cart 4 back to cartridge bay before I mount cart 7. About 10 min was lost due to this swapping. After setup the guiding stars for ET crew, I checked the Lindy cart, and found its front aluminum board was out of position. 10:10Z cart 5, plt E8029. stars on GTF. During exposure, telescope stop tracking with altitude "AB" and rotator "AO" on. There is NO too large to correct in fiducial cross window. We did not know who to bill for this tracking abortion. But an "axis init" and "goto field without gflat" get stars right back. After this two commands, there was a warning message in SOP window: WARNING: theta offset is large 336.37670112402139 > 180 arcseconds 12:00Z endNight rejocied. ---=== 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 39114, plate -9999 ------- 23:45 39114 0.0 bias 23:50 39115 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:15Z 8 8024 292.97 -0.0019 60.79 0.0019 125.34 -0.0025 1.000260 06:19Z 4 8026 193.72 0.0050 68.24 0.0009 19.56 -0.0021 1.000190 08:51Z 7 8022 199.01 0.0084 84.02 0.0015 20.31 0.0701 1.000150 10:34Z 5 8029 111.15 0.0017 80.77 0.0024 -74.96 0.0343 1.000030 ---=== 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 ------------------------------------------------------------------------------ 04:15Z 8 8024 1.00026 -2568 -955 20 293 60.8 11.4 15 239 -- 1.2 06:19Z 4 8026 1.00019 -1876 -409 10 194 68.2 10.9 15 267 -- 1.1 08:51Z 7 8022 1.00015 -1481 -30 80 199 84.0 8.8 14 263 -- 1.2 10:34Z 5 8029 1.00003 -296 903 30 111 80.8 8.1 11 257 -- 1.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:22Z 61 17 22 236 (SW) 2429 - clear 23:55Z 59 15 14 222 (SW) 2088 - clear 00:27Z 59 15 13 212 (SSW) 1968 - clear 00:58Z 56 13 21 226 (SW) 2047 - clear 01:30Z 54 11 15 231 (SW) 1767 - clear 02:02Z 52 9 18 217 (SW) 1934 - clear 02:34Z 52 8 14 225 (SW) 1795 - clear 03:06Z 52 8 16 236 (SW) 2031 - clear 03:38Z 53 7 19 239 (WSW) 1978 - clear 04:08Z 52 6 11 255 (WSW) 1931 - clear 04:40Z 52 6 17 228 (SW) 1958 - clear 05:13Z 51 8 18 232 (SW) 1694 - clear 05:45Z 51 7 12 259 (W) 1679 - clear 06:17Z 51 7 11 261 (W) 1651 - clear 06:49Z 50 7 12 265 (W) 1561 - clear 07:21Z 49 6 11 265 (W) 1606 - clear 07:53Z 49 7 11 265 (W) 1758 - mostly clear 08:25Z 48 7 14 251 (WSW) 1623 - mostly clear 08:57Z 47 7 10 255 (WSW) 1694 - 09:30Z 47 8 12 275 (W) 1888 - 10:02Z 46 8 7 271 (W) 1753 - 10:34Z 46 10 15 267 (W) 2161 - 11:06Z 46 10 13 267 (W) 2059 - 11:38Z 45 10 12 266 (W) 2107 - 12:10Z 45 11 11 270 (W) 2243 - ---=== TELESCOPE STATUS ===--- 01:02Z Doors and louvers opened, fans on. 03:15Z enclosure off, cart 8 mounted. 11:45Z enclosure on, door and louvers closed, fans off. elescope parked at 121,30 with Cart 9 (Plate E8025) mounted Counterweights at 250 Spectro autofill reconnected No interlocks bypassed Dewar weights at 12:05Z Imager: 84 lbs 17 psi Spectro: 239 lbs 21psi ---=== SOFTWARE USED ===--- IOP/SOP: v4_21_0 Watcher: v2_34_0 MCP: v6_3_1 TPM: tpm_v3_3_0 AstroDa: v15_11_1 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: SoS: hoggPT: plate-mapper: ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A -5.8500 -5.8440 Axial B -5.6760 -5.6770 Axial C 0.9440 0.9420 Trans D -10.0010 -9.9940 Lateral E 10.3759 10.3759 Lateral F 11.9507 11.9380 GALILS Commanded: 4700. -2450. 3000. -7800. 3300. 3000.
