APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday September 21, 2008 (MJD 54731) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Dan Oravetz Scott Fleming (MARVELS) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We had clouds and some light rain the first few hours and then conditions improved and we were able to do some spectroscopy until high humidity forced our closure again. The humidity eventually decreased and we observed a MARVELS pre-selection plate at the end of the night. SEGUE: Finished cart. 1, 3131. MARVELS: Observed cart. 5, 3030 and cart. 9, 3033. (commissioning plates) Finished cart. 6, 3038A. (pre-selection plate) ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working properly.

Collimate numbers in Problems section. We had clouds and intermittent light rain, so we did not begin ventilation. Night: ----- 01:05Z - Sunset. 03:54Z - The clouds cleared out. Began ventilation. Doors and louvers opened, fans on. 04:09Z - Opened. Enclosure off. Cartridge 1, 3131, segue ************************ 04:29Z - gotoField.

Guide stars found on gotoField. 07:02Z - MARVELS exposure. 6 minutes. MARVELS test ------------ They wanted to check the throughput if the guide stars weren't perfectly centered. Stopped guider. Telescope provided +1 offset in D so the guide stars were slightly below center relative to the SAOImage display. We monitored this offset-tracking with gcam snapshots to make sure that the stars stayed where we hoped they would and they did. 07:13Z - MARVELS exposure. 9 minutes. 07:22Z - Started the guider. Centered the guide stars. Stopped guider and issued -1 offset in D so that guide stars were slightly above center. 07:25Z - MARVELS exposure. 9 minutes. 07:36Z - Started the guider. Centered the guide stars. Stopped guider and issued +1 offset in A so that the guide stars were slightly right of center (East is to the left in the image). 07:41Z - MARVELS exposure. 9 minutes. 07:52Z - Started the guider. Centered the guide stars. Stopped guider and issued -1 offset in A so that the guide stars were slightly left of center. 07:55Z - MARVELS exposure. 9 minutes. 08:05Z - Calibs. Cartridge 7, 3042, Marvel-pre ***************************** 08:35Z - After mounting cart. 7 and during the gotoField, the dewpoint depression fell to 2.3C and we closed. 08:40Z - Enclosure on, doors and louvers closed, fans off. 10:25Z - Humidity decreased and we opened.
