                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Clearing skies at sunset were hopeful signs that we'd be able to open
tonight, but the high humidity moved in soon after. The humidity looked
like it was going to stay below the limit for a bit around midnight. I
gave it 15-20 more minutes to stabilize and it shot back up over the limit
just after 1 am and stayed there till morning. At 4 am we were at 100%.
