The phenomenon of a supermoon occurs when the Moon is at its closest point to Earth, known as perigee. This happens in sync with a full Moon, making the Moon appear larger and brighter in the night sky. The Moon’s orbit is not a perfect circle, leading to variations in distance from our planet.
Understanding the Supermoon
A supermoon occurs due to the Moon’s elliptical orbit. Here are the key characteristics:
- Perigee: The closest point of the Moon to Earth.
- Full Moon: This phase amplifies the brightness of the Moon.
During this event, the Moon’s enhanced visibility draws attention, particularly in clear skies. Enthusiasts often capture stunning images of the supermoon.
The 22-Degree Halo
Occasionally, observers may notice a glowing ring around the Moon. This ring, known as a 22-degree halo, forms when light interacts with high-altitude ice clouds. This optical phenomenon occurs when moonlight passes through ice crystals, bending and reflecting the light.
Such halos can signify changes in weather, often forecasting incoming rain. Folklore commonly associates the appearance of a 22-degree halo with the saying, “rain real soon.”
Recent Supermoon Observations
On Friday morning, high ice clouds moved over southern England, allowing the halo to be spotted clearly. This coincided with the supermoon event, drawing significant interest from sky watchers.
Weather Implications
The presence of these ice clouds suggests a shift in weather patterns. Rain was predicted to spread across most regions of the UK as the day progressed, alongside strengthening winds.
In conclusion, a supermoon provides a breathtaking view, while weather phenomena such as the 22-degree halo can offer insights into upcoming changes in conditions.
