              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Rain and more rain (and a little hail too).  We had a clearing (sucker hole) around midnight but humidity was still too high to open safely.
I opened around 01:35 and clouds swamped us just as I started my focus sweep!  I closed again as I wasn't sure it these clouds were threatening or not.
We never opened again and I gave up at 05:00 with rain nearby.
