                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Clouds and a little rain near sunset kept us closed for a bit. The high
humidity began bouncing below the limit around 23:00, allowing us to open
after a while. Skies cleared nicely with good seeing rest of the night.
Spicam flats script seems to work beautifully.
