I turned on the enclosure fans at around 20:50 since we had high winds gusts (39MPH)/high humidity and lightning in the area earlier. I opened the enclosure at 21:10 under clearing skies. Seeing ranged from excellent (0.7 arc sec to medium 1.5 arc sec) thru the night.

Stars seemed well centered on the guider image and in the pointing model. Implemented new pointing model (TELMOD.DAT;32) Test 4: four 0.1s(?) exp with SPIcam RA 22:30:45.4 Dec +22:54:00.0 SPIcam images (0.1s) eng010705.0018 - FWHM 2.46 = 0.69 arc sec eng010705.0019 - FWHM 2.62 = 0.74 arc sec eng010705.0020 - FWHM - too short of exposure killed spicam eng010705.0021 - FWHM - too short of exposure killed spicam Guider images (5s) eng010705.0022 - FWHM 1.85 = 0.78 arc sec Test 5: Throughput ???
