Aligning Anomalies

The photos below show three mysterious orbs I photographed in Grand Central Terminal on May 12, 2017,  June 2, 2017, and May 10, 2017.  Note how all three orbs are aligned with the edge of a pillar. My photos show such orb alignments with an astonishing degree of frequency, much more than I would expect to see by chance. See here for hundreds of examples.
