odd radius plate arcs


35° plate arc in lower center, 24° plate arc above it and slightly to the right, and faint infralateral arc (?) at far left. The angular distances from the sun still need to be measured, however. Dalton Highway, northern Alaska, April 17, 2006. The photo has not been manipulated. Copyright Walt Tape.

A wider angle photo of the same display is here. A photo of another display, about 20 minutes earlier and ten miles further south on the highway is here; (then at "on assignment: arctic Alaska").

The display is almost too much for a man to bear. Conserning the first linked image, was there 22 upper tangent arc, or is that purely lower 20 plate arc?

It looks very interesting. Is this orginate in snow being thrown up or in diamond dust (by high air huminity)?

Greetings
