Red aurorae borealis

As winter finally fades here in the northern latitudes, so do the opportunities to witness displays of the aurora borealis.  Spectacular sightings were reported this year, including a seemingly inordinate number of reports of red auroras.

Top photo from a Reddit thread.  Below that one from a photoessay at the BBC.  The Telegraph has a photo of a similarly red aurora Australis.


  1. The green and red in aurorae are very specific colours since they arise from specific excitation states of atoms. I would say that these bright pink ones has just been tweaked in post-processing until the colour balance is well away from natural.

  2. Lovely colors. One day I do hope to get far enough north to enjoy that phenomenon.
