              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out clear, but a storm was approaching from El Paso by sunset. Aside from some passing clouds around 23:00, the storms never made it to us. We had clear calm weather until about 03:30, when the humidity began to spike.  The humidity went up and down several times, but never got bad enough to force a close.  We stayed open until it was too bright to observe.
