Super Blue Moon of August 2024: Know Everything About This Rare Event

Super Blue Moon, a rare astronomical event, occurred on August 19. The highly anticipated event hit the night sky after almost a year, as the previous Blue Moon was seen on August 30, 2023. But what exactly does that mean? Despite the exciting name, the moon is not blue, and the change in size is usually subtle. Understanding the definitions behind these terms can help set the right expectations for this unique event, even if it isn’t as visually spectacular as it may sound.

What is a supermoon?

A supermoon occurs when the full moon coincides with its closest approach to Earth in its elliptical orbit, known as perigee. When the moon is at or near this closest point, it appears slightly larger and brighter in the sky. However, the difference in size is usually subtle, with the moon appearing up to 14 percent larger at perigee than at its farthest point, apogee. This difference may be difficult to notice unless you are carefully observing the night sky.

What is a blue moon?

A blue moon is either the second full moon in a single month or the third full moon in a season that has four. The August 19th Blue Moon is of the seasonal variety. Despite the name, the moon does not appear blue unless there are specific atmospheric conditions, such as smoke or dust that scatter the light in a way that gives the moon a bluish hue. This is a rare occurrence and not something to expect during this event.

Do supermoons and blue moons always occur together?

No, they don’t. Supermoons happen multiple times a year, but blue moons are less common. The combination of a supermoon and a blue moon is rare, with an average of ten years between them. The next super blue moon won’t happen until 2037, making this a special opportunity for stargazers.
