"Anticrepuscular rays are sometimes seen enclosed by a rainbow. In this case they can be called wagon-wheel spokes."

Anticrepuscular Rays Observed Over Santos, Brazil Photographer: Meire Ruiz Santos; Summary Authors: Meire Ruiz Santos, Jim Foster
The photo above shows a beautiful display of anticrepuscular rays as viewed from the city of Santos in the Sao Paulo state of Brazil. It was taken near sunset, at 6:40 on February 8, 2018 -- the camera is facing east. The darker blue colored lanes are shadows, areas where clouds on the opposite horizon have effectively blocked the Sun's rays. Because there happens to be ample dust and aerosols in the air, the rays of sunlight and shadow project across the entire sky. Perspective makes it seem as though they converge at the antisolar point.
Photo Details: Camera: Canon PowerShot SX40 HS; Exposure Time: 0.017s (1/60); Aperture: ƒ/2.7; ISO equivalent: 320; Focal Length: 4.3mm; Software: Picasa.
Santos, Brazil Coordinates: -23.9561, -46.3264

Anticrepuscular Rays Over Melbourne, Florida
Photographer: Michael Seeley Summary Author: Michael Seeley
A few weeks ago I stepped out to watch the full Moon rise over the Indian River Lagoon near Melbourne, Florida. While waiting, I couldn’t help but notice these eye-catching rays. At first, I thought they might be somehow related to the Moon rising behind the building clouds, shown just above the eastern horizon. However, these are anticrepuscular rays, formed by sunlight streaming through cloud gaps near the western horizon that project across the entire sky. Perspective makes them appear to converge at the antisolar point, close to where the full Moon rises.
Photo taken on August 7, 2017. Photo Details: Photo taken at 8:16 p.m. about 9 minutes after sunset; ISO 800; f5.6; 1/125 sec. exposure.
