              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Welp, no luck tonight. I thought there might be a shot during A half but the clouds and eastern rain put a stop to that idea. Another thunderhead blossomed to the east and put radar everywhere at 4am, showing no signs of slowing down, so I called it.
No problems tonight.
