                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
Clouds, high winds, and high humidity prevented opening.  The humidity
dropped and winds dropped a bit (below closure limits) after 20:00 but
thick clouds (and threat of rain) prevented opening with the enclosure.
We also recorded a lightning strike! around 17:55.
 Observing Specialist, 2nd Shift: Russet McMillan
Continued clouds, high winds, and humidity.
