Another "Inverted V" Orb

The first of the 4 photos below shows a mysterious orb I photographed in front of a ceiling in Grand Central Terminal in New York on February 24, 2017.  The other three photos show mysterious orbs I photographed with a similar "inverted V" pattern.

Below is my updated table listing recurring patterns in mysterious orbs I have photographed  (most of the examples referred to below can be conveniently seen in this post).
