Photo date: December 23, 2016. Photographer: Mark Mahin.
I have taken hundreds of photos of speeding orbs at Grand Central Terminal (as you can see by watching these videos). The one below is among the most spectacular I have taken. We see a blue orb that is moving like natural things never move. At the top we see an extremely sharp turn of about 45 degrees. The camera has captured about 12 position states of an object moving very fast, which results in the "string of pearls" effect I have photographed more than 50 times (as shown here). The very sharp bend near the top proves that we cannot be seeing any type of hair or fiber, which would never have so sharp a bend.
