Why September's Corn Moon is also a 'Blood Moon' for UAE skywatchers

emirates7 - As summer wanes in the Northern Hemisphere, the night sky is set for a spectacular finale: the full Corn Moon, which will grace the skies on Sunday, September 7, 2025. While observers across North America will witness its warm, golden glow, other regions, including the Middle East, will see an even more dramatic event.

The Corn Moon: A Harvest Tradition
The term ‘Corn Moon’ comes from North America’s agricultural heritage, occurring during the peak of the corn harvest. Its bright light historically helped farmers work late into the night. It is sometimes mistaken for the Harvest Moon, which specifically refers to the full moon closest to the autumnal equinox—this year on October 7.

The Blood Moon: A Fiery Eclipse
Meanwhile, in parts of Asia, Australia, and the Pacific—including the UAE—a total lunar eclipse will turn the moon into a ‘Blood Moon,’ casting a striking red-copper glow. The full sequence, from the initial dimming to the peak of totality, will last over five hours, with the most intense red phase stretching for 82 minutes.

For UAE residents, this is a rare sight. The eclipse will be fully visible across all seven emirates, beginning on the evening of September 7 and continuing past 10:30 pm GST. In cities like Dubai, the best views can be enjoyed from open areas facing the eastern horizon.

Corn Moon vs. Blood Moon: Understanding the Difference
The Corn Moon is a traditional full moon, marking a time of brightness and harvest completion. In contrast, a Blood Moon occurs during a total lunar eclipse, when the Earth’s shadow entirely covers the moon. Its red hue is caused by sunlight bending through Earth’s atmosphere, which scatters shorter blue and green wavelengths, leaving the longer red wavelengths to illuminate the moon—essentially projecting all the world’s sunrises and sunsets onto its surface.

Looking Ahead
This celestial display signals the onset of autumn for stargazers and casual observers alike. Two weeks later, on September 21, 2025, a partial solar eclipse will be visible in New Zealand, Antarctica, and parts of the South Pacific, completing a cosmic sequence that bridges the end of one season and the beginning of the next.
