Red Orb at Night Is a Baffling Sight

Photo date: September 22, 2015. Photographer: Mark Mahin.

The photo below has not had any color adjustment, and shows a red orb above a building in New York City.  These red orbs are very rare, although this site has 52 photos of pink air orbs, 37 photos of orange air orbs, 168 photos of blue air orbs, 49 photos of green air orbs, and 101 photos of purple air orbs.

There was no fog, mist, rain, or precipitation on this night with very clean air. The air quality listed on airnow.gov was "good," with a rating of 23.
