Photo date: October 7, 2016. Photographer: Mark Mahin.
The photo below shows some mysterious orbs I photographed near the Chrysler Building in New York. The brightest orb seems to be resting on a building top. Notice there are no orbs near the bottom of the photo. It's the same "vertical bias" I've photographed many times before, with lots of orbs at the top of the photo and few or none at the bottom. This shows we are not seeing natural particles near the camera, which would be spread evenly around the photo area.
There was no fog, mist, rain or precipitation on this night. The air quality listed on airnow.gov was "good" with a rating of 32.
