              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Dembicky
Clouds tonight for first half.  I rans some Agile dark tests with our new Block filter installed
in the wheel.  Data can be found in /export/images/Q1APO/UT110107/agile/Darks & Biases (if needed)
Looks like eyelid closed and block filter in place is as good as dark slide in place (both will
full dome illumination with Br. Qrtz and Halide lamps on).  I would NOT recommend just the block
filter alone, with lights on in the dome.  The combination of eyelid and block worked very well
though.  I took both 60s and 300s darks
We opened at 00:10, but my observer reported that she couldn't see her object in 900s exposure
with the cloudcover.  I closed around 02:20 as there were radar returns nearby.
No problems tonight.
SPIcam heater turned back on low.
