Photo date: July 6, 2016. Photographer: Mark Mahin.
The photos below show two orbs photographed floating about indoors. Both have the same very distinctive-looking stripes. The top orb is particularly astonishing. Each stripe has a kind of "triple line" appearance in which we see thin lines above and below (or to the left and right of) the thick stripe (what is known as a shadow stripe). I defy anyone to produce a photo of a natural particle with the kind of thick stripes we see here.
here for a composite photo of 30 of these strange striped orbs.
