Northern Light Beam (NLB)
"Proton Arc", "Steve"

There are a few fuzzy names of some certain Northern Light´s apperances. E.g. "Proton Arc", "Steve". These names are not useful/valid because  there is no distinct point when the shape changes from an ordinary to this special category (!?) of apperance. Shapes of the light are abound. It is an arbitrary concept that discloses nothing. Also, the "Proton Arc" has no scientific support.

If one needs to descibe this "special" shape, an intuitive designation would be Northern Light Beam. "Northern Light" and "Light Beam" = NLB!

Eureka!

A weak, but distinct NLB,  far away from a classical northern green arch.
