Observers: S. Chung, J. Gerke, D. Berg Telescope Operator: S. Allanson Support Astronomer: Olga Kuhn Summary: The following programs were observed: OSU_RMAGN_PG0026, OSU_CHAOS NGC628_field1, UM_Scarlata C3_112, OSU_RMAGN_PG0052, UM_RMHstars_M33-045901, UM_RMHstars_M33-125093 and UM_RMHstars_M33C-15731. Weather: clear, calm wind, generally good seeing. Standard Star Wolf1346: UT 01:40 -- Start acquisition on Wolf1346 UT 01:44 -- Start obs, seeing is ~0.8'' Standard (Feige110) for OSU_RMAGN_PG0026+129: UT 02:21 -- Start acquisition on Tell_PG0026_UT2.acq UT 02:30 -- Start obs on Feige 110, seeing ~1.1 OSU_RMAGN_PG0026: UT 02:42 -- Start acquisition for OSU_RMAGN_PG0026 UT 02:51 -- Confirmatory image shows slight offset (by ~2.5 pixels) of source within the slit. Make offset from MODS GUI of 0.31 arcsec, and take another confirmatory image. UT 02:54 -- Source is now centered in the slit. Start obs. Seeing is ~1 arcsec. OSU_CHAOS NGC628_field1: UT 03:24 -- Start acquisition for NGC628_field1 UT 03:41 -- Start obs, seeing ~1.2 based on guide star, but probably better. UT 04:51 -- Seeing improved, ~1. UT 04:53 -- Error message on guiding window during the 4th exposure: "PCS transfer failed", but we appear to still be guiding. Guide star appears to be centered. UM_Scarlata C3_112: UT 05:55 -- Start acquisition for C3_112. Seeing worsened -- now at >1.5 arcsec and does not meet requested criteria. Therefore, move to OSU_RMAGN. Telluric standard (GD248) for OSU_RMAGN_PG0052: UT 06:04 -- Start acquisition for Tell_PG0052_UT5_UT10.acq. Seeing in this direction much better, ~0.8 arcsec. UT 06:12 -- Start obs of telluric, seeing ~1. OSU_RMAGN_PG0052: UT 06:28 -- Start acquisition for PG0052 UT 06:38 -- Source looks offset in the slit, so offset using MODS GUI by 0.27 arcsec (~2 pixels). Start obs. Seeing 0.8-1 arcsec. UM_Scarlata C3_112: UT 07:16 -- Start acquisition on C3_112, seeing ~1.3 UT 07:29 -- Manual offset by -0.123 arcsec (1 pix) to center the star in the slit. Blind offset within the acq script executed -- can see faint source in the slit. Offset by +1 pix. (equivalent to never having done an offset). UT 07:34 -- -Start obs. FWHM of guide star is ~1.3 arcsec, but probably the seeing is better than this. The acquisition field image shows star FWHM is ~0.9 arcsec. UM_RMHstars_M33-045901: UT 08:25 -- Start acquisition on UM_RMHstars_M33_045901 UT 08:39 -- Start obs, seeing ~0.9 arcsec. UM_RMHstars_M33-125093: UT 09:03 -- Start acquistion UT 09:14 -- Start obs, seeing ~0.9 UM_RMHstars_M33C-15731: UT 09:40 -- Start acquisition UT 09:49 -- Start obs, seeing ~0.7 ND_WHIMgals: UT 10:08 -- Start acquisition UT 10:24 -- Start obs, seeing ~0.8 Standard star gd71 UT 12:02 -- Start acquisition UT 12:10 -- Start obs, seeing ~0.7 Skyflats UT 12:57 -- Start skyflats -- Took 4 skyflats in the sdss_i filter.
