              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Focus started our variable between 1.7 and 2.7 at the start of the night.
We had some radar returns pop up suddenly so we closed at 01:48.  Although we didn't get any rain, radar was showing possible precipitation between us and El Paso which was just a little too close for my comfort to re-open, even though the sky was relatively clear overhead.  Around 03:30 clouds finally started forming overhead.  We called it for the night at 04:40 with not much change in the overhead clouds.
