APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday January 16, 2011 (MJD 55578) ---=== OBSERVING TEAM ===--- Elena Malanushenko Dan Oravetz Support: Steph Snedden Nathan DeLee ---=== OBSERVING PLAN ===--- MARVELS Science ---=== OBSERVING SUMMARY ===--- We lost a few hours at the end of the night to high winds (gusts peaked over 50 mph). Observed the following MARVELS fields: cart. 5, 4518A & B cart. 3, 4520A & B cart. 1, 4514A & B cart. 8, 4515A We relaxed M1 and the mirror numbers were in-spec, but M2 MiG values are reading 0 again in Axial B & C and Trans D. Looks like things got kicked into program mode again somehow. The galils were reasonable, so we proceeded normally. ---=== OBSERVING LOG ===--- Afternoon ========= 23:26Z - Verified that STUI actors were alive and responsive (except ecamera). 23:28Z - Turned on the ThAr lamp. 23:33Z - Began ventilation. 23:35Z - Checked out enclosure and telescope. 23:40Z - Checked fiducials. 23:45Z - Relaxed M1. M1 mirror numbers are in-spec. M2 Axial B, Axial C, and Trans D MiG values are reading 0, suggesting things have ended up in program mode again, but the Galil readings look reasonable. 00:06Z - Mounted cart. 5. Night ===== 00:25Z - Opened to partly cloudy skies. Forced a fill from the 180L LN2 dewars. 00:49Z - Calib. sequence. Cart. 5, 4518A, APG 120+04 ************************** 00:53Z - gotoField. Spectra 15 & 16 showed low S/N in all three calibration exposures. It appears this degraded S/N began sometime between Thursday (after Nathan left) and last night (we could see the low S/N in the images from the end of last night). 01:02Z - Used spiralPattern to acquire guide stars. 01:23Z - MARVELS science. Overcast (IRSC_sigma = 50) with 1.7" FWHM seeing. Note that spectra 15 & 16 have low S/N, but this is because the long fiber (#8, I think) from the telescope to the MARVELS instrument had low throughput in general, even in the cals. 02:14Z - We cleaned the gang connector and the calibration port with alcohol and a cotton swab per Nathan's suggestion. Prior to cleaning I had noticed a discoloration/film covering an area slightly larger than a fiber tip and after cleaning this was removed. We saw immediate improvement in the S/N in the subsequent cals. 02:15Z - Calib. sequence. S/N looks good in spectra 15 & 16. Cart. 5, 4518B, APG 120+08 ************************** 02:16Z - gotoField. Used spiralPattern to acquire the field. 02:30Z - MARVELS science. Mostly clear (IRSC_sigma = 13) with 1.7" FWHM seeing. 03:22Z - Calib. sequence. Cart. 3, 4520B, APG 180+08 ************************** 03:30Z - GSOGTF. 03:46Z - MARVELS science. Mostly clear (IRSC_sigma = 10) with 1.9" FWHM seeing. 04:38Z - Calib sequence. Cart. 3, 4520A, APG 210-08 ************************** 04:38Z - GSOGTF. 04:51Z - MARVELS science. Clear (IRSC_sigma = 7) with 1.7" FWHM seeing. 05:42Z - Calib. sequence. Cart. 1, 4514A, APG 195-04 ************************** 05:46Z - GSOGTF. 05:58Z - MARVELS science. Clear (IRSC_sigma = 7) with 1.5" FWHM seeing. 06:50Z - Calib. sequence. Cart. 1, 4514B, APG 195+04 ************************** 06:50Z - GSOGTF. 07:00Z - MARVELS science. Clear (IRSC_sigma = 5) with 1.8" FWHM seeing. 07:54Z - Calib. sequence. Cart. 8, 4515A, APG 210+08 ************************** 07:57Z - gotoField. Had a star in fiber 11, but not a guide star. Used spiralPattern to find the correct set of stars. 08:08Z - MARVELS science. Mostly clear (IRSC_sigma = 8) with 1.7" FWHM seeing. 09:04Z - Closed. The wind was gusting to 45 mph and the seeing was between 2.5" and 3.0". We remained ventilating. 09:08Z - Calib. sequence. We still have winds gusting near 50 mph (and some clouds have come in) and don't have time to get set-up on another field and finish a 50-min. exposure before 12-deg. twilight, so we called it a night. 11:45Z - Turned off ThAr lamp. 11:55Z - endNight finished. ---=== SPECTROSCOPY DATA SUMMARY ===--- Image Cart Plate Texp Exptype Object Seeing - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - T00:49:43.340 0 2. 255204. 6066.
