Are there incidents or concerns regarding human eye safety of aurora observers, on Earths surface or airborn?
The light from auroras is very dim, so there is no possibility of being harmed by auroral light, either on the ground or airborne. Auroras are often so faint that they can’t even be seen until your eyes become dark adapted, that is, until your iris opens wide and the sensors in your eyes relax and become more sensitive. This may take 10 or 15 minutes. The aurora is beautiful, but can be faint! Dr.
