APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday August 20, 2009 (MJD 55064) ---=== OBSERVING TEAM ===--- Elena Malanushenko Alaina Shelden Steph Snedden Kaike Pan ---=== OBSERVING PLAN ===--- Engineering ---=== OBSERVING SUMMARY ===--- Humid, cloudy and dusty all night long. Didn't open. Autofil systems worked as they should. Loaded fiducial tables, and home/relaxed the mirrors. MCP is now v6_6_0. Will try for optical collimation and pointing model tomorrow if weather permits. ---=== OBSERVING LOG ===--- Afternoon: --------- 00:33Z Waiting for word on if we can take the telescope. We will have to fill the spectrographs. 00:34Z Started imager biases. 00:36Z We can take the telescope! 01:08Z Checkout went fine, fill stopped as it should. Can't start ventilating yet, the dust count is too high (1.0 micron, 4039 and rising) Night: ----- 01:39Z Sunset 02:04Z Haven't ventilated yet, the dust is now up to 7048 and there are clouds. We've checked the fiducial tables, which all look fine. We're waiting for the MCP bug to be fixed before we load them. 03:07Z Evening twilight (18 deg) 03:13Z Home/Relaxed mirrors successfully. All errors are within the margins. 03:52Z Radar returns also visible. Just to add to the bad weather... 04:06Z Dust getting lower, but still ~7000. Still cloudy with radar returns. 04:21Z Dust at 8653, humidity at 62.8%, temp at 15.6C 04:56Z Loaded the new fiducial tables. Now on MCP v6_6_0 and fiducial v1_81. 08:45Z Dust and humidity are still very high (especially humidity) and we still have clouds. Since we can't finish optical collimation or a pointing model in our time left, we were given permission to call it a night and go home. 08:48Z endNight finished...and there was much rejoicing. (yay) 11:08Z Morning twilight (18 deg) 12:36Z Sunrise ---=== IMAGING RUN SUMMARY ===--- 8005 00:31Z 00:47Z 100 O 46.40 50.41 39 bias ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- ---=== LTMATCH RESULTS ===--- ---=== SPECTROSCOPY DATA SUMMARY ===--- ---=== TELESCOPE OFFSETS AND SCALE I ===--- ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- ---=== WEATHER LOG ===--- 00:47Z 59 47 23 61 (ENE) 3126 - clouds/dust 01:19Z 58 47 20 72 (ENE) 4061 - 01:51Z 57 47 21 69 (ENE) 6469 - clouds/dust 02:23Z 57 46 18 75 (ENE) 7482 - 02:55Z 56 47 27 68 (ENE) 8075 - 03:27Z 56 46 20 74 (ENE) 10538 - 04:00Z 57 46 27 74 (ENE) 8461 - 04:32Z 56 48 20 67 (ENE) 7275 - 05:04Z 55 47 28 70 (ENE) 8885 - 05:36Z 54 50 24 71 (ENE) 6244 - 06:08Z 54 51 20 82 (E) 5042 - 06:41Z 54 51 20 75 (ENE) 4894 - 07:13Z 55 52 21 74 (ENE) 5050 - 07:45Z 54 50 19 80 (E) 4530 - 08:17Z 53 50 17 75 (ENE) 4487 - 08:49Z 52 49 15 79 (E) 4021 - humid/dust/clouds ---=== TELESCOPE STATUS ===--- Didn't get to open or ventilate.
