A “bright ring around the moon” is a phenomenon that occurs when there are high, thin clouds in the atmosphere. These clouds are made up of ice crystals, which refract and reflect the light from the moon, creating a halo-like ring around it.
The size and brightness of the ring can vary depending on the size and density of the ice crystals in the clouds. This phenomenon is also sometimes referred to as a “moon halo” or a “22-degree halo,” because the ring is approximately 22 degrees in diameter. The appearance of a bright ring around the moon is often considered a beautiful and eerie sight, and has been the subject of many myths and legends throughout history.
When we see a bright ring around the moon, it’s called a lunar halo or moon halo. This phenomenon is caused by the refraction and reflection of light through ice crystals in the atmosphere.
When the moon’s light passes through these ice crystals, the light gets bent or refracted, which causes it to spread out into a circle around the moon. The shape of the ice crystals also causes the light to scatter in a way that makes the halo appear brighter on the inside edge.
Moon halos are typically seen when there are high, thin clouds in the sky, which contain ice crystals. They can occur in any season, but are most common during winter months.
Moon halos are a beautiful and fascinating sight to see, and they have been the subject of many myths and legends throughout history.
