Subject: 2.5m obslog 20070630 (MJD 54282) Date: Sun, 1 Jul 2007 05:52:00 -0600 (MDT) From: swatters@apo.nmsu.edu (Shannon Watters) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday June 30, 2007 (MJD 54282) ---=== OBSERVING TEAM ===--- Shannon Watters Justin Crepp Suvrath Mahadevan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, some rain, and nearby radar returns prevented us from opening until late. We obtained signal on cart 9 and had a problem with a guide fiber on cart 2 (see problems) so we didn't get any signal on it. ---=== OBSERVING LOG ===--- Afternoon: --------- All ET systems checked and working. Night: ----- 09:05Z Cart 9, E8028. NGSOGTF, FK5 used. Seeing ~1.0" 50 minute exposure. 10:10Z Cart 2, E8032. NGSOGTF. Couldn't find an FK5 either. It turns out that fiber 10 wasn't plugged in (see problems) and we ran out of time. ---=== 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 45588, plate -9999 ------- 02:42 45588 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 ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 08:46Z 9 8028 1.00000 0 1257 0 121 30.0 18.7 4 318 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 02:41Z 65 34 6 115 (ESE) 643 - cloudy 03:13Z 65 38 13 82 (E) 660 - cloudy 03:44Z 65 37 14 77 (ENE) 762 - cloudy 04:18Z 66 36 14 44 (NE) 733 - cloudy 04:50Z 65 35 15 70 (ENE) 788 - cloudy 05:22Z 66 34 13 61 (ENE) 731 - cloudy 05:53Z 67 34 12 67 (ENE) 760 - cloudy 06:23Z 66 35 14 60 (ENE) 816 - cloudy 06:53Z 66 35 11 55 (NE) 742 - cloudy 07:27Z 64 36 5 357 (NNW) 781 - cloudy 07:59Z 64 35 5 13 (NNE) 669 - cloudy 08:31Z 66 34 1 342 (NNW) 753 - cloudy 09:02Z 65 34 2 338 (NNW) 749 - partly cloudy 09:34Z 64 35 1 24 (NNE) 705 - 10:06Z 65 36 2 12 (NNE) 736 - 10:38Z 62 35 4 257 (WSW) 711 - 11:08Z 63 37 1 246 (WSW) 849 - 11:38Z 61 38 1 212 (SSW) 982 - partly cloudy ---=== TELESCOPE STATUS ===--- 02:00Z Doors opened, fans and blowers on, louvers open. 08:40Z Enclosure off. 11:00Z Enclosure on, doors closed, fans and blowers off, louvers closed.

We opened the cart and found guide fiber 10 wasn't plugged in but fiber 7 was (even though the guider camera complained -- see errror above). We plugged it back in but it was too late to get a data point (~10:30Z and our cutoff is 11:00Z).
