              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started cloudy, with radar showing passing rain. We did not open right away. By 1am radar returns had ceased (or at least weren't headed toward us). We opened. The skies were not clear, but the observer's targets were bright enough to observe. The clouds thickened, and rain showed up on radar again around 4:50.  We weren't getting science returns, so we closed up, and did not open again.
