OSU/RC Queue Observing: UTC 2010 Mar 18 =========================================== ========== Observers: ========== Peter Garnavich (ND), Matthias Dietrich (OSU), Rachael Beaton (UVa), Katherine Rueff (ND) Observing Assistent: Wayne Wack Support Astronomer: Olga Kuhn Instrumentation: Doug Officer ========== Instrument: ========== LBC ============= Quick Summary ============= ** Evening Sky Flats may be suspect due to problem with the offsetting in the SkyFlat Scripts *** UTC 01:36 -- Sunset; Blank field RA 5:56:00 Dec +04:09:00; looks photometric UTC 01:51 -- Sky flat UsV; 0.6sec in U; 0.3sec in V x 5 exposures UTC 01:54 -- Test flats in Bessel B, R; 1 sec exp; look good, doing 5x B,R flats; 1 sec exp. UTC 02:03 -- Test flats Bessel V,I; 1 sec exp; look good, doing 5x B,R flats; 7 sex exp. UTC 02:10 -- LBC communuicatoion problems, no slewing capabilities UTC 02:24 -- Communication came back online; now checking the pointing and collimation. UTC 03:28 -- Collimation almost finished, telescope moving towards zenith to work on LBT mech. prob (alarm with LUCIFER set off) UTC 03:51 -- LUCIFER problem fixed, LBC allowed to continue; Collimating at high elevation ~85 degrees. UTC 04:01 -- Collimating at low elevation ~85 degrees UTC 04:17 -- Checking pointing by slewing to starpgarnavi (at) nd (dot) edu near first target; OSUmonitor/NGC2903, then collimated, and inspecting the focus UTC 04:40 -- The focus seems to be difficult, but we are going to start aquiring the first target; OSUmonitor/N2903 =================== OSUmonitor/NGC2903 =================== UTC 04:44 -- slewing to OSUmonitor/NGC2903 running focus script ---> seeing varies between ~0.7 to 1.1 arcsec continues to iterate UTC 04:58 -- Focus and collimation finished for red and blue UTC 05:00 -- Started OB script for OSUmonitor/NGC2903 UTC 05:09 -- on lbcr: 0.9" seeing; not seeing the blue images; error message: "too few pixels to be downloaded" trying to determine if it is an OB problem or a LBC-Blue problem 2 images taken: lbcr.20100318.050048.fits (0.9") & lbcr.20100318.050639.fits (1.1") UTC 05:14 -- Stopped OB. No blue data is being taken. Blue was selected as "master" and we are changing the OB so that the Red is the "master" to see if this fixes the problem. UTC 05:15 -- Re-starting the OSUmonitor/NGC2903 OB with change to LBC-Red being the master arm. UTC 05:17 -- OB Stopped because it did not do any setup of the instrument on either arm. Running a 25 bias script. Still no blue channel, but red is working. Blue arm "thinks" it is working and is incrementing images. Disabled & Reenabled the LBC; Rebooting the camera control. UTC 05:26 -- Restarted the camera, rerunning bias script UTC 05:28 -- Redoing the Focus Script for NGC2903 UTC 05:35 -- Focused converged- 0.8" B 0.5" R; OB Script started again.
