On Sunday, September 21, 2025, a partial solar eclipse will grace the skies as the Moon passes between the Earth and the Sun, partially obscuring the solar disk. This eclipse unfolds as the Moon reaches the descending node of its orbit, aligning just enough to cast its shadow near—but not directly onto—Earth’s surface. With a magnitude of 0.855, a substantial portion of the Sun will appear covered for viewers in specific regions. Unlike a total solar eclipse, where the Moon’s shadow traces a narrow path of totality across the Earth, a partial eclipse results when the central, darkest part of the Moon’s shadow—the umbra—misses the Earth entirely. In this case, only the lighter penumbra sweeps across our planet, producing a solar “bite” rather than full immersion. This particular eclipse will be best observed across parts of Oceania and Antarctica, where partial coverage will range from modest to striking. In fact, observers near the southernmost point of New Zealand and on Stewart Island will experience up to 80% of the Sun’s disk obscured during the morning of Monday, September 22 (local time). This will result in noticeably dimmer light and a crescent-shaped Sun—a thrilling sight even for seasoned skywatchers.
