On the night of September 29, 2023, a full moon will coincide with a lunar eclipse, offering a captivating celestial display visible from various regions across the globe. Depending on your location, observers may witness the moon take on a reddish hue, commonly referred to as a “blood moon,” during the eclipse.
The full moon will reach its peak at approximately 11:57 UTC. As it rises, the moon will enter the Earth’s shadow, leading to the eclipse. This phenomenon occurs when the Earth positions itself directly between the sun and the moon, blocking sunlight from reflecting on the moon’s surface. During this event, the moon may appear to glow red, a result of Rayleigh scattering of sunlight through the Earth’s atmosphere.
Viewing Opportunities Across the Globe
The lunar eclipse will be visible in various parts of the world. In Australia, it can be seen in its entirety, beginning around 17:14 AEST. North and South America will also have excellent views, particularly in regions where the sky is clear. According to NASA, the eclipse will last for approximately three hours, making it a prime opportunity for stargazers and astronomy enthusiasts alike.
For those in Europe and Africa, the full moon will rise just after the eclipse has begun, so visibility may be limited. Observers are encouraged to check local timings to ensure they catch the spectacle. Clear skies will enhance the viewing experience, so enthusiasts should consider heading to areas with minimal light pollution.
Why the Moon Turns Red
The striking red color observed during a lunar eclipse is due to Earth’s atmosphere filtering and refracting sunlight. As the Earth’s shadow gradually moves across the moon, the remaining sunlight bends around the planet. This process scatters shorter wavelengths of light, such as blues, while allowing longer wavelengths, like reds and oranges, to reach the moon.
This event is not only a visual treat but also an opportunity for scientific observations. Astronomers often study these occurrences to gain insights into the Earth’s atmosphere and its effects on light.
For many, the September full moon and lunar eclipse will serve as a reminder of the beauty and complexity of our solar system. As the world gazes skyward, it presents a moment for reflection and connection with nature.
