UT 20120918 AO#2 Commissioning

Observer: Buzoni,L, Esposito, S. Riccardi,A. (INAF)
Telescope Operator: Bechetti,G (LBTO)
Additional AO Support: JCGuerra,. Christou,J. (LBTO)
Telescope Support: (LBTO)
Instrument Support: (LBTO)

Summary

  • Night time operation of the AO#2.

  • Check of the AO system working at bin 3 and bin 4. Check performances and robustness of the system.

  • Many skip+RIP of the system. Most of the rip came from the change of the seeing conditions.

  • Changes in the wfs software to improve the robustness of the acquire reference star and the estimation of the reference star magnitude.

  • Hard failure of the active optics after 12:05 UT. The PSF couldn't be collimate at two different elevations and objects.

  • Seeing variable 2" to 0.8"
