              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The mirror covers needed a reset this afternoon.  There was lighting in the area and I assume it causes a hiccup in power.
I don't know HOW we managed it but we stayed open the entire night.  We were surrounded by clouds, fog, lightning, rain and yet we prevailed!  However, I can't remember the last time I minesweeper clicked so fast through all weather windows and all night long.  My eyes!  8-(
No problems tonight.
