Comments = SDI went berserk during the night. Early on, it was running fine, though the winds look cloud-damped. I think the trouble arose due to arcing of the intensifier high-voltage supply, due to condensation in its cooled housing. Arcing causes the intensifier's internal protection circuit to force it to shut down. MC-Nov-1998.
