---++++ Night logs and results
*7/24/07 UT* <br>
Clear, excellent seeing.  Completed laser and BTO setup for first 4 hrs.  Then measured bright star performance (~30% Strehl at K), observed several science targets, and measured vignetting on LOWFS.  Laser stable at 5.0 W, FWHM=2.3". [[%ATTACHURL%/palm_lgs_log_070724.pdf][palm_lgs_log_070724.pdf]]

*7/26/07 UT* <br>
Partly cloudy, excellent seeing.  AO acquisition camera power supply failed.  Used temporary power supply and software integration of video signal.  Unable to focus LLT or acquire faint stars.  Observed one LGS  and several NGS science targets.  Laser 5.0W at start, 4.5 W and end of night.  [[%ATTACHURL%/palm_lgs_log_070726.pdf][palm_lgs_log_070726.pdf]]

*7/27/07 UT* <br>
Partly cloudy, excellent seeing.  6 AO software crashes during night.  Observed 2 LGS targets and several NGS backup targets, with frequent interruption by clouds.  Laser power 7.0 W at start, 6.9 W at end of night, FWHM=2.6".  LGS return significantly improved (200 cts @ 150 Hz.) [[%ATTACHURL%/palm_lgs_log_070727.pdf][palm_lgs_log_070727.pdf]]
