              ------------- ACTIVITY LOG --------------
Observing Specialist: R.DeColibus
Rain, humidity, and dust conspired to keep us closed all night. When it
wasn’t any of the above, there was precipitation too close for comfort on
radar for pretty much the whole night.
With no real prospects for opening, we gave up around 05:00.
