INAF LBC MODS queue observing, 2013 January 20-21

Observer: M.Faccini, F.Cusano
Telescope Operator: G.Bechetti
Support Astronomer: O. Khun
Instrument: LBC + MODS


At the beginning of the night thick clouds at the horizon, cirrus all over in the sky, moon 63% illumination, seeing 0.8. Starting with LBC. Problems with LBC, elongated stars in the blue channel. Trying to solve the problem. Mostly clear in the middle of the night. Switch to MODS.

01:39 slew to pointing field of CalchiNova 3A

01:47 dopfia first

01:58 launched M31_Focus.ob

02:01 elongated stars in both channel

02:05 changing z4 manually

02:06 dopfia X2

02:14 we try an exposure test with position angle zero, it did not work, stars still elongated in the blue channel

02:40 dopfia again *it's impossible to take science data in this condition *we decide to try to solve the problem due to the high ranking projects (Grazian 30) foreseen at the end of the night. Other MODS programs are in constraints at 7 UT currently we have only LBC targets *we are discussing the problem with the italians AO *we take images at different focus to understand if the features rotate

03:20 calling John Hill

03:44 dopfia

04:07 trying to correct manually (astigmatism)

04:17 dopfia and manual correction

05:44 slew to Clementini 21, Leo T

*05:50*After the test we reach a better quality for the images in a new field about 52deg
  • the results are not good for the Clementini field.
  • according with the situation and with the difficulties encountered (and also with the evaluation of the SA) we switch to MODS for the rest of the night.
  • the quality of the images is not useful for the Science prog. of this night *The technical data acquired during this test will be useful to solve the "elongation" problem for the next run.
