Another Repeating Pattern in Striped Orbs

 Below we see some mysterious orbs I photographed at Grand Central Terminal in New York. The first photo below was taken on September 27, 2016.  The second photo (posted here) was taken on September 1, 2016.  The third photo (posted here) was taken on July 13, 2016. Notice that all three have an "exclamation mark" pattern, with a small circle underneath a line.  The second and third orbs are "dead ringers" for each other. This is one of numerous cases I have identified of a repeating pattern in orbs. You can see other cases by looking at this series of posts.
