At the beginning of the night we stay close due to high humidity. Sky covered. We could perform 4 hours of observation only. We had to stop due to high humidity.

03:50 The TO opens the dome
  • Waiting for collimation
  • Mirror too warm (DT=4C)


04:40 Slew to Gilli Q2
  • acqMODS 4Q2_J1048_M2_MOS.acq.
  • Seeing 1.8"

  • the average seeing is 1.7" at the beginning of the integration
  • the average seeing is nearly 2" during the first part of the integration of the second frame
  • active optics errors, we go on integrating with the last image.

06:14 the TO cancels the preset and tries to collimate, so we have to acquire again. After the collimation the seeing is really better (average seeing 1.2").

07:40 TO CLOSES the dome due to humidity

11:45 TO opens the dome again and tries to collimate
  • humidity 40-45%
