It’s worth noting that the moon can sometimes appear larger due to an optical illusion known as the “moon illusion.” When the moon is near the horizon, it can appear larger because our brain compares it to nearby objects, such as buildings or trees. When the moon is high in the sky, there are no such reference points, making it appear smaller.
What is a super blue moon?
A super blue moon is a combination of three lunar phenomena: a full moon, a blue moon, and a supermoon. The term “blue moon” refers to the third full moon in a season with four full moons, or the second full moon in a calendar month. This August’s blue moon falls under the seasonal definition. It will not appear blue; the term “blue moon” is a misnomer, as its name stems from a historical misinterpretation of the lunar cycle.
Gordon Johnston, retired NASA program manager, explained: “Although it will not appear blue, it will be a Blue Moon, as the third full moon in a season with four full moons. The first recorded use of the English term ‘Blue Moon’ dates back to 1528.”
How to observe the Super Blue Moon
The super blue moon will be visible at 11:56 pm IST on August 19 and will be full in the sky for the next three days. For the best viewing, find a place with minimal light pollution and a clear view of the horizon. Experts recommend using a telescope or binoculars to improve visibility and see more details of the moon’s surface. Be sure to check the weather forecast to ensure clear skies.
Upcoming Supermoons
In addition to the super blue moon in August, three more supermoons are planned for 2024. The Harvest Moon will appear on September 17th and will be partially obscured by the Earth’s shadow. The Hunter’s Moon follows on October 17th, and the last supermoon of the year is on November 15th. Each of these moons offers a unique opportunity to observe celestial events.
Significance and rarity
The super blue moon is a rare event. Such a combination of supermoon and blue moon occurs irregularly, about every 10 to 20 years. The next occurrences of a super blue moon are predicted to occur in January and March 2037, making the August 2024 event extra special for sky enthusiasts. This supermoon is especially special because it coincides with Raksha Bandhan, a traditional Indian festival that celebrates the bond between brothers and sisters. As you enjoy the festivities of the festival, take a moment to look up and witness this extraordinary celestial event.
