Another Undulating Orb in Grand Central Station

Photo date: February 26, 2015. Photographer: Mark Mahin.

The photo below was taken in Grand Central Station in New York.

Note that the very strange object at top. It is an orb making an undulating, snake-like motion.

There are three types of orb motions that are inexplicable, because we know of nothing in nature that moves in such a way. The first such motion is when orbs make sharp right-angle turns. See my posts labeled "orb right angle turn" for 14 such cases. The second such motion is when orbs make sharp u-turns. See my posts labeled "orb u-turn" for 3 such cases. The third such motion is when orbs make this type of undulating motion.  See my posts labeled "air orb undulation" for three other such cases.
