Photo date: May 12, 2017. Photographer: Mark Mahin.
Below we see two photos I took at Grand Central Terminal in New York. Both show a mysterious blue orb near a flag edge. The orb in the top photo is aligned with the edge of the flag. This is the 52nd time I have photographed a mysterious orb exactly aligning with a flag edge (see here for the other 51 photos). The orb in the bottom photo is aligned to a wall. I see such orb alignments very, very frequently at this location, much more frequently than I would expect to see by chance. See here for more than 200 examples.
