Good morning RP. Today's Astronomy Picture of the Day (APOD) is titled "Anticrepuscular Rays Converge Opposite the Sun." In meteorological optics, rays of sunlight that appear to radiate from the point in the sky where the Sun is located are called crepuscular rays. Anticrepuscular rays are those rays of sunlight that extend across the sky and appear to converge at the opposite point (much like railroad tracks that appear to converge in the distance). In this image taken from an airplane, anticrepuscular rays are seen converging at a point opposite the position of the Sun. It looks like something bright is shining at a point near the image center, but light is actually streaming in...not out.

Thank you, my friend Maj William W. 'Bill' Price for posting the Astronomy Picture of the Day (APOD) for June 24, 2019 entitled "Anticrepuscular Rays Converge Opposite the Sun."

This is an intriguing image to me.
"Explanation: Is there ever anything interesting to see in the direction opposite the Sun? Sometimes there is. Notable items include your own shadow, a shadow of the Moon during a total solar eclipse, a full moon -- in eclipse if the alignment's good enough, a full earth, planets at opposition, glints from planets, the gegenschein from interplanetary dust, the center of a rainbow, hall-of-mountain fogbows, an airplane glory, and something yet again different if your timing, clouds and Sun position are just right. This different effect starts with clouds near the Sun that are causing common crepuscular rays to stream through. In the featured rare image taken from an airplane in mid-April, these beams were caught converging 180 degrees around, on the opposite side of the sky from the Sun, where they are called anticrepuscular rays. Therefore, it may look like something bright is shining at the antisolar point near the image center, but actually it is reverse-shining because, from your direction, light is streaming in, not out."
Thank you, my friend Maj Marty Hogan for mentioning me.
