              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We were closed all night for clouds, radar, particles, and also Rain, Glorious Rain!  Which was fortunate since there was a new fire start, probably from lightning.  Not too close to the observatory, and progres has already been made on containment.  But it's nice to have a good reason for being closed, at least!
