Photo date: March 17, 2017. Photographer: Mark Mahin.
In the photo below we see an orb that seems to be behind the fence at the bottom. This is one of many photos I have published showing orbs behind distant obstructions. Such photos help to refute claims that orbs are tiny specks near the camera (a claim that is untenable for the physical and mathematical reasons discussed here).
There was no fog, mist, rain or precipitation on this night. The air quality listed on airnow.gov was "good."
