Mauna Kea VIS closed for the time being

[TomK]

Apparently, it was one bolt of lightning that split into three branches that did all the damage. It took out the VIS step-down transformer, lots of electrical and electronic systems plus the phone network while also setting off all the fire alarms at Hale Pohaku.

Anyway, power was restored late this afternoon, and the VIS should be open again on Friday.
