              ------------- ACTIVITY LOG --------------
Observing Specialist: Obs Spec
Evening started partly cloudy with the threat of rain on the radar. We risked an opening for apollo. Very soon more rain appeared on radar headed for us, so we closed at 20:25. The danger of rain passed, and we opened again at 22:14. Seeing was good, and the weather stayed clear.  No problems tonight, and we stayed open all night after our initial closure.
