A partial eclipse of the Sun occurs on Sunday 21 September, 2025 UT, lasting from 17:29–21:53 UT. This will be a deep partial eclipse, with 86% of the Sun covered for viewers closest to the center. This will provide a significant spectacle for those who will see it in New Zealand, the southern Pacific, and parts of Antarctica.
The timings of the phases of the overall eclipse
worldwide are as follows. In any particular
place it will be seen for a significantly shorter
duration as the shadow moves across the Earth:
| Partial eclipse begins: |
17:29:32 UT |
| Maximum eclipse: |
19:41:44 UT |
| Partial eclipse ends: |
21:53:33 UT |
During this eclipse the Sun will be 0.531° in apparent
diameter, 0.4% smaller than average. The Moon will be just 4 days before apogee, making it very small.
At maximum eclipse it will be 0.501° in apparent
diameter, which is 5.6% smaller than average. This has no real
effect on this eclipse, since the Moon's central
shadow misses the Earth, making this a partial eclipse.
The statistics page has information on the ranges of the sizes of
the Sun and Moon, and the Moon data page displays detailed
information on the Moon's key dates.
New Zealand will see a deep partial eclipse, with close to 70% of the Sun covered in the north, and 80% in the south, just as the Sun rises.

Note that while all dates and times on this site (except
where noted) are in UT, which is within a second of civil time,
the dates and times shown in NASA's eclipse listingsGSFC Eclipse Web Site
The primary source of all the information on eclipses presented here at Hermit Eclipse. (NASA Goddard Space flight Center)
are in the TDT timescale.
The Sun and Moon distances are shown in km, and as a
percentage of their minimum - maximum distances; hence 0%
is the closest possible (Earth's perihelion, or the
Moon's closest possible perigee) and 100% is
the farthest (aphelion, the farthest apogee).
