OSU/RC Queue Observing: UTC 2010 Mar 17 =========================================== ========== Observers: ========== Rick Pogge (OSU), Matthias Dietrich (OSU), Chris Howk (ND) Observing Assistant: David Gonzalez Huerta Support Astronomer: Olga Kuhn Instrumentation: Doug Officer ========== Instrument: ========== LUCIFER ============= Quick Summary ============= (1) Calib : skyflats in J,H,K internal flats (2) Science : ND_sn09dc twice as long as planned OSU_mgiant SDSS-54919-3308-150 (SDSS14) (cirrus, clouds) tried OSU_SN2008S but lost guide probe several times Time Lost: - weather ~2.5 hrs - instrument ~1.5 hrs - telescope 0.0 hrs Worked all night with LUCI1 imaging and long-slit programs. Lost ~1.5h to faults with the mask exchange system that required intervention by LUCIFER team members to clear. Cirrus came in late and shut down the last 2.5h of the night. ============== Detailed Notes: ============== UTC: 02:18 -- sun set Starting Sky Flats UTC 02:07 -- running flatk.txt script to take sky flats, cirrus is moving in from the west, sky still too bright, cts ~30000 UTC 02:12 -- flatK 2 sec 3x UTC 02:14 -- flatH 2 sec 3x; too bright UTC 02:17 -- flatK 4 sec 3x; ca. 23000 cts UTC 02:18 -- flatK 4 sec 3x; ca. 22000 cts UTC 02:19 -- flatK 4 sec 3x; ca. 21000 cts UTC 02:21 -- flatK 4 sec 3x; ca. 15000 cts UTC 02:23 -- flatK 4 sec 3x; ca. 10000 cts UTC 02:24 -- flatH 2 sec 3x; ca. 10000 cts UTC 02:25 -- flatH 4 sec 3x; ca. 18000 cts UTC 02:26 -- flatH 4 sec 3x; ca 14000 cts UTC 02:28 -- flatJ 2 sec 3x; ca 8000 cts UTC 02:29 -- flatJ 5 sec 3x; ca. 19000 cts UTC 02:30 -- flatJ 5 sec 3x; ca. 15000 cts UTC 02:31 -- flatJ 7 sec 3x; ca. 16000 cts UTC 02:33 -- flatH 10 sec 3x; ca. 9000 cts UTC 02:34 -- flatH 15 sec 3x; ca. 14000 cts (star trails) skyflat J-band 15 H-band 12 K-band 12 UTC 02:38 -- started pointing; picked pointing star: load catalog and picked a star first high elevation start ds9 and iraf epar LBTtools LUC epar ptcorr set sequence number follow the instructions checking low elevation, pointing is fine =========== OSU_MGiants =========== UTC 02:55 -- slew to the position of the rv standard star HD90861 and using this star to do the focus UTC 03:19 -- started OSUmgiant.scriptrvstd.obs slit NB26 ---> had to be changed to NB6 in the OBscript directory UTC 03:29 -- start OSUmgiant.scriptrvstd.obs slit NB6 lost by accident the instrument control panel logout completely and started lucifer from the beginning UTC 03:46 -- LUCIFER up again and OSUmgiant.scriptrvstd.obs slit NB6 started Lucifer has problems with mask change - gui goes red; possibly the same problem as yesterday night ---> calling Walter Seifert UTC 04:45 -- We got Walter Seifert on the phone and then on skype It seems that a strange error has happened and Walter needs to contact a software engineer, i.e. Peter UTC 05:25 -- starting a test script to see what happens while Walter tries to get a hold of Peter to fix the mask problem we switched to imaging ========== ND09dc SN ========== UTC 05:34 slewing to the filed of SN2009DC UTC 05:38 started the observing script slight cirrus is moving through seeing is about 1.2 arcsec J-band 30sec 3x 24 positions UTC 06:33 since we have no news about the slit we repeat this script ============ OSU Mgiants ============ UTC 07:23 moving to the telluric standard star HR 4875 check pointing using ptcorr UTC 07:28 OSUmgiant.scripttelstd1.acq UTC 07:37 to re-start skycat, logout of lucifer and re-start lucifer again UTC 07:41 OSUmgiant.scripttelstd1.acq UTC 07:51 OSUmgiant.scripttelstd1.obs HR 4875 seeing ~0.9 arcsec UTC 07:57 wavelength calibration UTC 08:02 ff-calibration REMARK In the readme file it was not clear whether the ff and arcs should be also taken for the standards. Since this is very time consuming we interpreted that it should be only done for the target stars, i.e., the science objects UTC 08:14 SDSS-54919-3308-150 (SDSS14) slewed to the object FeII filter for acquisition made it hard to see the star replaced it with a H filter (possibly cut-and-paste relict) cirrus moves through UTC 08:33 started the science script 180sec 10x 2 positions cirrus is getting thicker, clouds are moving in from the west UTC 10:28 started arc-script UTC 10:35 started ff-script =========== OSU SN2008 =========== UTC 09:41 slewing to target, however clouds in this direction of the sky UTC 09:46 started the integrations seeing ~1.1 arcsec guide probe lost, clouds offset fault UTC 09:54 re-started the script, failed no guide-probe UTC 10:06 re-started the script, however, guide probe faint, low transparency (clouds) UTC 10:09 guide probe lost, clouds, failed offset sky basically overcast ---> starting the end of night calibrations UTC 11:05 started the dark script specdark.txt 2s 25x o2dcr 4s 25x o2dcr 5s 25x o2dcr 7s 25x o2dcr 10s 20x o2dcr 15s 20x o2dcr 30s 20x o2dcr 180s 10x o2dcr 180s 10x mer SkyFlats at the end of the night -------------------------------- none because of the cloud cover
