This very rare picture shows a chemical generated aurora that comes from two NASA Rock probes launched over Northern Norway (Aurora Zone Upwelling Rocket Experiment)
additionally a light natural aurora can be seen.
A continuously growing album of photos that IMHO reveal the awesome and seldom-seen beauty of the railroad world from the dimming of day to dawn's early light! From dusk to dawn, trains roll on! (I'm still finding gems of sunset-to-sunrise surprises!)
