The 9th Time I've Photographed This Pattern in a Mysterious Orb

Photo date: February 8, 2017. Photographer: Mark Mahin.

The photo below shows a mysterious orb I photographed in front of the ceiling of Grand Central Terminal in New York.

This is the ninth time I have photographed a mysterious orb with a pattern looking like this, in which we see a small circle shape underneath a thick vertical stripe stretching from the top of the orb down to about the center of the orb. Below are 8 other orbs I have photographed with the same pattern, which rather resembles an exclamation mark.

 This pattern recurrence is one of only about a dozen that I have documented. 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).
