                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Although we had a little snow during the day, less than 0.5" onsite, skies cleared
as sunset approached. Winds stayed high, sometimes reaching 37 mph gusts during
first half but we saw no ill effects facing away. Second half winds eased down but
seeing blew up, ~3.0" often.
TSPEC power supply switched during the day. Checkout darks look normal.
First half observer took some characterization data for Agile during twilight.
Pointing was good with both NA2 instruments.
