A very deep partial solar eclipse will occur at 19:43 UTC on September 21, primarily visible from Antarctica, New Zealand, and parts of southern Australia. The eclipse magnitude is 0.8550, with up to 85% of the Sun\u2019s diameter obscured at maximum and approximately 79.7% obscuration of the solar disk.<\/p>\n
The partial eclipse will begin at 17:30 UTC, reach maximum at 19:43 UTC, and end near 21:54 UTC.<\/p>\n
Auckland, New Zealand will see about 60% of coverage, Wellington 66%, Christchurch 69%, and Invercargill 72%. However, in some Antarctic regions the coverage will approach 80%.<\/p>\n
This eclipse belongs to Solar Saros 154, specifically member 7 of 71 in the series.<\/p>\n
Saros 154 began with a partial eclipse on July 19, 1917, and will end with another partial on August 25, 3179. Of its 71 members, 56 are umbral eclipses, including 17 annular, 3 hybrid, and 36 total. The previous eclipse in this series occurred on September 11, 2007, while the next, on October 3, 2043, will be annular.<\/p>\n
At the time of this eclipse, the Moon will be about 4.6 days before apogee, resulting in a slightly smaller apparent lunar diameter. The event occurs at the Moon\u2019s descending node, with the shadow axis passing south of Earth\u2019s center by 1.065 Earth radii (gamma = \u20131.0651).<\/p>\n
This will be the final solar eclipse of 2025, following a total lunar eclipse earlier that month.<\/p>\n
In 2026, two significant solar eclipses are expected; an annular eclipse on February 17 over parts of Antarctica, and a total eclipse on August 12 visible across the Arctic, Greenland, Iceland, and Spain.<\/p>\n
