              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
It rained a lot during the afternoon, and we were in and out of fog throughout A-half.
While the clouds cleared during B-half, the humidity never dropped low enough to open at any point during the night. We called it a night at 04:45.
