INAF LBC+MODS queue observing, 2012 February 20-21

Observer: K. Boutsia, M. Fumana
Telescope Operator: D. Gonzales-Huerta
Support Astronomer: D. Thompson
Instrument: LBC+MODS

Summary

Mostly clear skies at sunset. Some clouds in the west. We do flats anyway, since we point to the east.

At the beginning of the night we tried the program with the Non-Sidereal tracking and even though we did manage to track, the offsets set in the OB were ignored, so we could not exactly accomplish what the PI wanted.
We tried to change the ephemeris, in order to account for the offsets, but we saw that this also did not work exactly as expected, so we aborted the program.
In total 6 images per band were obtained with NS tracking but centered on the JPL coordinates. Total time spent (wasted??) on this project 45min.

The rest of the night has been un-eventful, with good seeing (0.8-1.0").
We finished Bedin, Bellazzini and 1 field of the Gilli program.

02:10 set NSIGUI and send OB: 20120218E0

• abort because we had kept guiding active and it lost the guide star
• send again without guiding
• dimm seeing 1.3"
• it does not actually take the offsets set in the OB - only the position angle!!

02:18 set NSIGUI and send OB: 20120218E1

02:23 set NSIGUI and send OB: 20120218E2

• kept on going until 20120218E4

02:49 set NSIGUI and send OB again with modified ephemeris!!: 20120218E0

• it did not really change as much as we were hoping for
• we need to tell the PIs, either that they have to make an ephemeris for each offset OR try again when BP15 will be operational
