The Third "J" Letter I've Photographed in a Mysterious Orb

Photo date: March 30, 2017. Photographer: Mark Mahin.

Below is a photo I took showing a mysterious orb near a window in Grand Central Terminal.

Note that the stripe in this orb makes a "J" shape. As shown here, two days earlier I had photographed a mysterious orb that also had such a "J" stripe.  Below we see both of these orbs, along with a similar orb I photographed on June 22, 2016, as shown here.

Below is my revised table of 16 repeating patterns in mysterious orbs I have photographed (most of the examples referred to below can be conveniently seen in this post).
