Split Aura of the Blue Sky Orb

Photo date: May 7, 2016. Photographer: Mark Mahin.

The photo below shows a blue orb floating mysteriously above a building in New York City.  The moon was not visible on this night.

Below is a closeup. I seem to see a kind of split aura around the orb -- half purplish, and half red.

There was no rain, fog, mist or precipitation on this night. The air quality listed on airnow.gov was "good" with a rating of 28.
