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

08:44 WD_N6791_LONG_01 (Piotto)
  • seeing measured on images: blue:1.2"/red:~1.0"

09:17 dofpia

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
