A blue moon is set to illuminate the night sky this weekend. This event will mark the second full moon occurring within a single month. Typically, a blue moon appears every two to three years, and the next one is anticipated for 2037.
What is a Blue Moon?
The term “blue moon” refers to a calendrical blue moon, which occurs when two full moons happen in one month. The lunar cycle consists of eight distinct phases lasting about 29.5 days. This discrepancy sometimes results in an extra full moon within a calendar month. In some years, like 2018, two blue moons can occur.
Upcoming Blue Moon Details
This month’s blue moon is particularly special as it will also be categorized as a micromoon. A micromoon occurs when the full moon reaches its farthest point from Earth during its orbit. This blue moon will peak at 4:45 a.m. ET on Sunday.
- Date: May 28, 2023
- Peak Time: 4:45 a.m. ET
- Distance from Earth: Approximately 252,334 miles (406,093 kilometers)
- Average Distance from Earth: 238,855 miles (384,400 kilometers)
The Appearance of the Moon
Despite its name, the blue moon will likely appear silvery white or golden rather than blue. The term has a historical context, dating back to the 1500s, used to describe improbable occurrences.
On rare occasions, atmospheric conditions such as smoke or dust can make the moon actually appear blue. One notable instance was after the 1883 eruption of Krakatoa.
Viewing the Blue Moon
Different regions will observe the full moon at various times. In North America, Europe, and Africa, it will be brightest on the night of May 30. Meanwhile, viewers in Australia and Asia can expect the most brilliant display the following night, May 31.
Photography Tips
This time of year offers great opportunities for photography. As the moon rises between 5:30 and 6:30 p.m. local time, the skies will still be a beautiful blue, making for outstanding pictures.
In summary, May’s blue moon is not only a magical celestial event but also an excellent opportunity for night sky enthusiasts to marvel at the beauty of our lunar companion. Be sure to catch this spectacular spectacle!
