              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clouds, rain, lightning, high winds, and fog.  No chance of opening but I
got some bookkeeping and closed-dome testing done.
The 3.5m dewpoint sensor was stuck around 0 C despite several warming
cycles, so it may be something more complicated than a light coating of
ice.  The 2.5m dewpoint sensor appeared to be telling a more truthful
tale.
