INAF LBC+MODS queue observing, 2012 May 13-14

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

Summary

Some cirrus on sky at the beginning of the night.
The seeing has been very variable throughout the night (1.0" - 1.5").
For most of the targets, the red channel is marginally within specs and for the blue fwhm is usually 20% higher than requested seeing.
Towards the end of the night some frames for the N6791 project were very much elongated, even right after the dofpia.

07:37 EGS_USDT_R_6 (Nonino)

• seeing on the images ~1"
• dimm seeing 1.5"
• the wind is blowing directly into the dome...
• seeing is quite variable on the images

08:25 Slew to Piotto - FOCUS.ob is missing!!

• run dofpia using science OB
• we created a focus OB!!!
• wrong pointing offsets were sent and we cannot back them off
• dofpia again
• lbcrangebal

09:20 WD_N6791_LONG_02 (Piotto)

09:50 dofpia

09:54 WD_N6791_LONG_03 (Piotto)

• the last 2 reds are slightly elongated and also the last blue

10:24 dofpia

10:28 WD_N6791_LONG_04 (Piotto)

10:44 images are still elongated - abort OB

• point to the foucs OB that is less crowded and try dofpia there
• dofpia
• it took 5 iterations to collimate!!

10:52 WD_N6791_LONG_04 (Piotto)

• last images elongated - both blue and red

11:24 SA113_UsV_ri

• dofpia

11:37 Abort because sky is too bright

• start with flats
