UT 20130321 AO#2

Observer: D.Miller (LBTO),J. Christou(LBTO),JC,Guerra(LBTO)
Telescope Operator: Geno.B.(LBTO)
SW Support: (Tucson)
AO Support: (LBTO)
Telescope Support: Kevin N (LBTO)

Summary.

  • Active Optcs phase III test on sky. More details in the commissioning twiki.
  • The AO#2_SX on sky.
  • AO#1 on DX still in the lab. Planning to back on telescope Saturday.
  • Arcetri on skype;Enrico Pinna and Lorenzo Busoni available.
  • Sky mostly cover by clouds and seeing poor and variable; 1.3" to 2" measured from SH.
  • Moon: 73% of Full
  • DIMM not running.

Issues found:
  • Presets failed three times due to bay side stage time-out error. Two times was the X axe and one time Y axes.
  • Bad seeing mode didn't set the proper re-constructor.

Details.

The night started with Sextractor Phase III Active optics taking one hour. During this time the sky was cloudy and seeing was poor.

Power on the WFS from the AOs gave an error:

 WfsArbitrator_26847|ERR|       177|2013-03-22 05:58:35.226478|             MAIN > Exception: Timeout waiting for slopecompctrl.L.STATUS 

The BCU interface susbprocess was down.

The WFS is power off and w_stop/start.

After the restart the system, the power on from the AOS was fine. Not problems. System ready to go on sky.

Change star.

The sky too bad and it is getting difficult for the active optics to collimate.

Bad seeing mode

Selected the bad seeing mode from the AOS. From the log we can see that the table for the bad seeing it wasn't applied. A configuration file check is needed.
