An Orange Purple and Green Orb

Photo date: June 4, 2015. Photographer: Mark Mahin.

The photo below was taken in New York City, and shows a rather large orb at the top.

Below is a closeup of the orb at top (I used the IrfanView "Auto-adjust colors" menu option on this closeup). We see an orb that has three colors in different parts of it: purple, green, and orange. That's not something one sees in dust particles.

There was no fog, mist, rain, or other precipitation on this night.  The air quality listed on airnow.gov was "good," with a rating of 25 (anything below 50 is rated as good).
