STEVE and Mt Clements Photo Print

This rarely seen phenomenon was captured at Logan Pass in late September. It was once commonly referred to as a “Proton Arc” but now scientists call it S.T.E.V.E., which is an acronym that stands for “Strong Thermal Emission Velocity Enhancement”. This atmospheric phenomenon tends to coincide with the Aurora Borealis but it’s much less predictable, infrequent and it appears to have different behavior and properties. The milky way is visible coming across the proton arc with Mt Clements and Mt Oberlin in front of both. Truly a once in a lifetime capture in Glacier National Park.
