Subject: 25m Obslog 2000-04-26 (MJD 51661) Date: Thu, 27 Apr 2000 03:12:56 -0600 (MDT) From: hayes@apo.nmsu.edu (Jeffrey Hayes) Wednesday April 26, 2000 Apache Point Observatory SDSS 2.5m Observing Log (MJD 51661) OBSERVING TEAM: =============== Dan Long (APO) Jeffrey Hayes (APO) Beng Chen (JHU) VISITORS: ========= Jim Gunn (PU) Connie Rockosi (UC) Andrew Connolly (UP) Steve Kent (FNAL) Robert Lupton esq. (PU) John Peoples (FNAL) Bill Boroski (FNAL) et alia. THE PLAN: ========= Science with the Imager if it is photometric and good seeing; spectroscopy if not. SYNOPSIS FOR NIGHT: =================== A decent night was had by all. Imaging the whole of the night in quite decent seeing (1.2 to 1.6''). A focus sweep in decent seeing was obtained. TELESCOPE STATUS: ================= DIMM: ----- 1.4'' at 19:30 0.7'' at 20:30 1.5'' at 21:00 1.6'' at 21:30 1.6'' at 22:00 3.0'' at 23:30 2.5'' at 00:30 INTERLOCKS: =========== none bypassed SOFTWARE USED: ============== IOP/SOP: v3_13_1_branch_1 Watcher: v2_8_2 MCP: v4_2_4 TPM: v1_0_8 AstroDa: 14_24 TCC: 2.2.5 WEATHER SYNOPSIS (see below for hourly data): ============================================= Clear at the start; clouds to S and W. Wind at 2 mph from the North. Seeing from anything from 1.2'' to 2''. GENERAL COMMENTS (see Problems below for details): ================================================== Very nice seeing tonight. The visiting committee came, saw and seemed to be moderately impressed. Connie volunteered to nake sure that endNight ran correctly when she awoke in the morning. We started the beast at 03:10. We also moved the focus sweep data from run 1413 to sdsshost:/data/astro/long/1413 (see below). The telescope was closed up at 02:45 without mishap.
