Two Triangles, One of Them Explicable

Photo date: April 6, 2015. Photographer: Mark Mahin.

Below we see a photo of the top of the Chrysler Building in New York.

We see a triangle of mysterious purple orbs near the Chrysler Building. It's something similar to what was shown in this image, which also shows a triangle of purple orbs near the Chrysler Building.

See my posts labeled "full spectrum camera photo" for additional photos of mysterious orbs floating around at night. When I shoot with a full spectrum camera, these things appear abundantly in the night sky. 

There was no precipitation, fog or mist on this night, and the air quality listed on airnow.gov was "moderate" with a number of 55, close to the number of 49 that would qualify as "good."
