What is a Supermoon Partial Lunar Eclipse?
The evening of Tuesday, September 17th will bring a special treat for skywatchers as the Harvest Moon graces the night sky with a partial lunar eclipse. This event marks the last lunar eclipse of the year, making it a must-see for astronomy enthusiasts. A partial lunar eclipse occurs when the Earth moves between the sun and the moon, casting a shadow on our rocky satellite. Unlike a total solar eclipse, where the sun is completely blocked, during a partial lunar eclipse, only part of the Earth’s shadow will move across the moon. This unique phenomenon allows us to witness the moon glowing red instead of its usual white glow.
The Significance of the Harvest Moon
The September Harvest Moon holds special significance due to its proximity to the autumnal equinox on September 22nd. Named not for the month, but for its aid to farmers during the harvest season, the Harvest Moon rises just after sunset, providing extra light for those working in the fields. According to the Farmer’s Almanac, the Harvest Moon rises around the same time each night, unlike other moonrises throughout the year. This celestial event has long been celebrated for its practical benefits to agriculture, marking the changing of seasons and the abundance of the harvest.
Exploring the Supermoon Phenomenon
What makes this partial lunar eclipse even more special is that it coincides with a supermoon. A supermoon occurs when the moon becomes full at the closest point in its orbit to Earth, making it appear 14% larger and about 30% brighter than a typical full moon. This unique celestial alignment enhances the visual spectacle of the lunar eclipse, captivating viewers with its larger-than-life presence in the night sky. The gravitational force of the supermoon also has a subtle impact on Earth’s tides, creating slightly stronger tides than usual, though the effect is minimal, causing changes of just a few inches.
As the partial lunar eclipse unfolds on the night of September 17th, observers will have the opportunity to witness the moon as it transitions through different phases of shadow and light. Beginning at 7:41 p.m., the eclipse will reach its maximum coverage at 9:44 p.m., before concluding at 11:47 p.m. Unlike a total solar eclipse, no special equipment is needed to safely view a lunar eclipse; all you need to do is look up at the moon and enjoy the celestial show unfolding above.
The last lunar eclipse occurred on March 25, 2024, and the next visible lunar eclipse is scheduled for March 13, 2025. This upcoming lunar eclipse will be a total eclipse, where the Earth will cast a shadow over the moon, completely blotting it out from view. In 2025, another total eclipse is set for September 7th, though it will not be visible from North America, adding to the rarity and exclusivity of these cosmic events.
As we prepare to witness the spectacle of the supermoon partial lunar eclipse on the evening of September 17th, let us marvel at the wonders of the universe and the intricate dance of celestial bodies that captivate and inspire us. Whether you’re an avid stargazer or simply curious about the mysteries of the night sky, this event offers a unique opportunity to connect with the cosmos and experience the beauty of a celestial phenomenon that has fascinated humanity for centuries.
