              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had fog and rain all day and I didn't anticipate being able to open this evening.  However, about an hour before sunset, the clouds began clearing and we focused our enquiring eyes to the sky! The humidity was mighty (85%) during the first half of the night but it did not dampen our spirits!  Our enemy fled to 45%...only to return with a vengeance near dawn and attacked us from all fronts in number exceeding 90%.  Nonetheless, We were able to persevere and make it 12 deg twilight before shedding tears of dew upon the many keys of our little kingdom and retreated in defeat.  Yet, in that time, we saw far and well (almost 1"!) and we mark this night...a victory.
No problems tonight.
