May 23-26, 2007 LGS observing run

Night logs and results

5/24/07 UT
Laser and BTO setup until 10:00pm. Then checked LLT boresighting no adjustments necessary) and performed some LGS performance tests in partly cloudy conditions. Imaged two science targets at the end of the night. Partly cloudy, seeing ~0.50" in V. 5/24/07 night log

5/25/07 UT
LLT collimation in partly cloudy conditions until 1am. Found LGS and NGS imaged through LLT at 3.5" FWHM, reduced to 2.5" after optimizing collimation (in 0.6" seeing). Shuttered for 2 hours by USAF Space Command. Performanced testing for last 2 hours, in cleear skies. Laser power 5.0 W all night. 5/25/07 night log

5/26/07 UT
6 science targets. Variable seeing. Laser power constant around 5W. 5/26/07 night log

5/27/07 UT
4 science targets, Laser power constant at 5W. Seeing ~0.6 in V. BTO problems meant we lost ~4.5 hours of potential LGS time. During the lost LGS time 2 hours of backup NGS programs were executed. 5/37/07 night log
