Subject: 2.5m obslog 20120818 (MJD 56158) From: asimmons@apo.nmsu.edu Date: Sun, 19 Aug 2012 10:37:04 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday August 18, 2012 (MJD 56158) ---- Observing Team ---- Dan Oravetz Audrey Oravetz ---- Observing Plan ---- Pointing Model ---- Observing Summary ---- We were closed for most of the night. The weather conditions improved for 3 hours, barely enough time for us to obtain a 100-pt pointing model, however the results were not great. We implemented it anyway and will perhaps test it tomorrow. We ran the APOGEE autoscheduler, but no new MJD was visible on the webpage. Do we know which cart to observe during twilight? The dewar for SP1 will need replacing soon (at 94lbs when we left this morning), but if it makes it until the afternoon we can swap it when we get up. ---- Observing Log ---- Afternoon: ========== Checked out telescope and software. All working properly. Took BOSS cals, biases and darks. Focused collimators. Took APOGEE evening cals. Did not start ventilating due to nearby storms. Night: ====== 05:11Z - Started ventilating. Mounted engineering camera. Force filled spectrographs. Moved telescope to 70 degrees for homing/relaxing. We decided to do this while the mirrors were reaching equilibrium, and to wait while nearby storms passed. 05:45Z - Began to home and relax the mirrors. Checked mirror numbers again. Everything looks great. 06:06Z - Opened enclosure. Connected engineering camera and established communication. 06:21Z - Test slew. Crossed fiducials. 06:40Z - Took ecamera dark, flat. Focused the camera. Checked the center - needed to adjust the instrument block 0DEG;40 image center to llm_Ctr 595 520. 07:12Z - Began pointing model, GRID_10_10_20_88_T_90.DAT;1. Some clouds, but mostly clear. Seeing ~1.5" (most of the time). Point #2 was saturated @ 5s exposure time. Point #28 (gimg-0049) was a double star. Points #65, #76, and #96, the stars were not able to be found. 09:05Z - Finished pointing model, but was forced to close right afterwards because the humidity rose over the limit. We noticed the humidity spiked when there was ~15 points left on the model. We did several touch-tests around the telescope and surrounding area during this time to make sure that the telescope was safe. We also kept a very close eye on the temperature of the mirror. The dew point on the mirror never dropped below 2.2. We closed the enclosure, stopped ventilating, and replaced the engineering cartridge with cart 10. 09:08Z - Results of the pointing model: * getdat[tcc.pterr]pterr_20120819.DAT;1 Read 97 data points * fix * use ie ia pzz1 an aw ca * fit Sky RMS = 4.34 Popn SD = 4.48 *use *fit Sky RMS = 3.27 Popn SD = 3.51 The results are not the greatest (several outliers reading 4-10"), but we implemented the new model anyway. We figure that we can test the model tomorrow (weather depending), and if it is not at all useable, we can alter the model to remove the greatest of the outliers, or we can attempt to take a new model altogether. 10:10Z - Ran the APOGEE autoscheduler, but the MJD did not show up on the page? Started APOGEE morning cals. 10:36Z - Humidity still high, and not enough time to reopen and test the model. We turned everything off. ---- Telescope Status ---- 05:11Z - Began ventilation. Doors and louvers opened, fans on. 06:06Z - Opened enclosure. 09:05Z - Enclosure is on, doors and louvers are closed, and fans are off.
