				ACTIVITY/FAILURE   LOG
The dome was not opened due to ice on the done shutter and enclosure.
Considerable snow and ice was melted today, warm and sunny, but
enough ice remained at the crown of the shutter to warrant remaining
closed.  The concern, specifically, was that the ice could be
dislodged by  wind and fall within the enclosure.
The good news is that another 2-3hrs of good sunshine should melt
all remaining ice.  The forecast looks good for tomorrow night.
