INAF LBC+MODS queue observing, 2012 May 15-16

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

Summary

Clear skies at the beginning of the night.
The seeing has been variable and >1.5" so after 3hr with LBC we switched to MODS where we had programs that could be in spec.
At the end of the night, we switch to LBC again, because of no available targets on MODS and we had AGAIN the same problem with the elongated images. The direction of elongation changes from chip to chip.
During the Piotto project we keep having the elongation problem. This time we run dofpia AND lbcrangebal before EACH OB, but it does not help!!.

10:40 Abort because images are elongated

10:41 dofpia and lbcrangebal - dofpia

10:52 WD_N6791_LONG_08

• half images are elongated!!! - we are not sure of the reason.
• we have run dofpia and lbcrangbal before each OB - it does not solve the problem.
