              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
The night started out with rainshowers from 19:00-20:00, then a small break for an hour andf a half, and another shower at 21:45.  Cleared somewhat, and the radar returns evaporated, allowing us to risk an opening at 01:20.  It proved to be too cloudy to get useful data, and we closed again at 02:09.  While doing an inst swap at 03:00, skies cleared almost instantly (seriously, from mostly cloudy to completely clear in 10 minutes!), and we were able to open for OU03.  Clouds forced a clousure once again at 05:30, and we stayed closed.
