The dome was not opened due to snow on the enclosure and heavy snowfall.
The SPICAM dewar has lost it's vacuum.  During an auto-fill, the
fill tube was blown from the dewar, causing many liters of LN2 to
shower the dewar.  The dewar became very cold, and as a result, the
vacuum was lost.  Spicam has been allowed to warm to ambient and
will be addressed today by Jeff Morgan.
