				ACTIVITY/FAILURE   LOG
The dome was not opened tonight due to ice accumulation on the
dome shutter, rails, and roof.  Though clear and sunny today,
temperatures were well below freezing and sufficient melting did
no occur.  Forecast is for warmer temperatures
through the weekend.  Hopefully, this will be sufficient to melt
the frozen precip. on the enclosure.
