              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Most of the night featured heavy clouds and some rain sprinkles.  Second half the clouds lightened, but the humidity rose at the same time.  I had the observer stop for humidity just before twilight began, although otherwise he could have continued observing a bit longer.
The Colorado observers are onsite, training student Maya Yanez.
