The last round of full moon in the summer of 2025, known as the “Sturgeon Moon,” tenderly made its appearance in the night sky around the world on Saturday, August 9th. Due to its close proximity to the horizon, this full moon not only presented a more spectacular viewing effect but also underwent a change in color.
The name “Sturgeon Moon” comes from the traditions of Native Americans, as the end of summer is the season when sturgeons in the Great Lakes region of North America are at their fattest, and for centuries, these fish have been an important food source for the indigenous people.
This full moon reached its peak phase at 3:55 a.m. Eastern time in the United States on the 9th (3:55 p.m. Taiwan time), allowing astronomy enthusiasts and the public around the world the opportunity to witness this celestial feast of late summer. This round of full moon also signifies the change of seasons, hinting at the arrival of autumn and longer nights for stargazing.
The best time to observe the Sturgeon Full Moon is at moonrise during local sunset, when the moon hangs low on the horizon, making it appear larger than usual. This is a visual phenomenon known as the “Moon Illusion.” When the moon is low in the sky, moonlight needs to pass through a thicker layer of atmosphere, resulting in hues of orange, pink, or even red halo, reminiscent of a sunset, adding a romantic atmosphere to the full moon.
Observing the full moon does not require special equipment, but the viewing location should be chosen away from city light pollution, such as in the mountains or by the sea.
