OSURC run June 25 - July 1 UT June 24-25 to June 30-July 1 civil First night: UT 2014 June 25 Observers: Scott Adams, Don Terndrup (OSU) Support Astronomer: Olga Kuhn Telescope Operator: Steve Allanson Tonight begins with cirrus and some thicker clouds, but clearing conditions. There are clouds forming in various directions on the satellite map, so conditions are nonphotometric to start. There is also a considerable amount of smoke to the west, and a smell of smoke on the air. STARTING INSTRUMENT: MODS LONGSLIT Mask images to checkout instrument. Several of these masks are in MODS from a previous run.

We will acquire ND_v418ser to see what the conditions are. 04:29 UT: Have pointed at the target. The designated acquisition and guide star is too faint for the current conditions. The guiding is still working, but it may be possible we would lose guiding if the seeing degrades or clouds come in. The PA=0 acquisition script was not present in the OB files, so we re-created it from the other scripts. 04:37 UT: Seeing is a little better, so we will proceed.

Have more filter errors, this time on the red side. Restart script 10:19 UT: No other targets before twilight stars, so we are running the observation script again to double the number of exposures on this field. Now to wait a bit for twight flats. 11:15 and beyond: r and g sky flats. Not all have sufficient counts. 11:55 Starting calibration. Notes on those files will be appended. Night was photometric at end.
