April 23-27, 2007 LGS observing run
Night logs and results
4/24/07 UT
Closed due to fog until 2:30am, then opened for NGS engineering due to low laser power (3W). Conditions clear, seeing ~1.0" in V. Completed most NGS tests planned for run.
4/24/07 Night Log.
4/25/07 UT
Cancelled night for laser due to low power (2.5W). Conditions clear, seeing ~0.7" in V. Completed all remaining NGS tests and several science targets.

4/26/07 UT
Scattered high clouds, seeing 1.0"-2.0" in V. Engineering and NGS science until 00:00 (boresighted LLT, laser tuning). LGS science for remainder of night. Laser 4.3W, unstable by end of night. 3 science targets observed.

4/27/07 UT
Full night of shared-risk science observing. Conditions: Clear, seeing 1.0-2.0". Acquired 10 LGS targets, ~7 observed successfully with K FWHM=0.20-0.30". Laser 4.3-5.4 W, stable. A spectacular
time lapse movie was taken by Scott Kardel.
