Photo date: April 26, 2017. Photographer: Mark Mahin.
The photo on the left shows a striped speeding orb I photographed at Grand Central Terminal in New York. This is the 290th striped orb I have photographed in dry air (see here for the other 289 photos). The photo on the right (cropped from the rightmost edge of a larger photo) shows another speeding orb I photographed at the same location.
