What are these rays of light coming from the East?

The rays of light observed coming from the East during sunset are most likely a phenomenon known as anticrepuscular rays. These rays appear opposite the sun and radiate from the horizon, creating striking beams of light converging towards the sun's position on the opposite horizon. Anticrepuscular rays are similar to crepuscular rays, which are the more commonly known sunbeams seen radiating from the sun itself, usually at sunrise or sunset. However, while crepuscular rays extend outward from the sun, anticrepuscular rays appear to converge toward a point on the horizon opposite to the sun, creating the illusion that they come from the East when the sun is setting in the West. This optical phenomenon occurs due to the scattering and diffraction of sunlight by atmospheric particles such as dust, water droplets, or clouds. The parallel rays of the sun are bent and scattered by these particles and appear to converge due to linear perspective effects. Although these rays seem to diverge from a single point, they are actually parallel. Understanding this helps to explain why photos taken facing East during sunset show these mysterious rays of light — they are the continuation of crepuscular rays extending across the sky and converging on the opposite horizon. This natural display highlights the interaction between sunlight and atmospheric conditions, which can vary with weather, cloud cover, and pollution levels. Observations like these provide fascinating insights into meteorological optics and help enhance our appreciation of natural light phenomena. If you encounter such rays, it’s a perfect moment to capture stunning photographs or simply enjoy the beauty of atmospheric science in action. Such sightings remind us of the complex and beautiful interactions between sunlight and our environment.
