A total eclipse of the Sun occurred on Saturday 4 December, 2021 UT, lasting from 05:29–09:37 UT. The Sun was darkened for 1 minute and 54 seconds by a dramatic total eclipse covering a very broad path, 419 km wide at maximum. This was a sight worth seeing, and was visible from Antarctica. The partial eclipse was visible in Antarctica and South Africa.
The timings of the phases of the overall eclipse
worldwide are as follows. In any particular
place it would have been seen for a significantly shorter
duration as the shadow moved across the Earth:
| Partial eclipse began: |
05:29:11 UT |
| Total eclipse began: |
07:00:01 UT |
| Maximum eclipse: |
07:33:22 UT |
| Total eclipse ended: |
08:06:29 UT |
| Partial eclipse ended: |
09:37:24 UT |
During this eclipse the Sun was 0.541° in apparent
diameter, 1.5% larger than average. The Moon was at perigee, making it very large.
At the start and end of the eclipse the Moon
was 0.558°, and at maximum eclipse 0.561°,
which is 5.6% larger than average; hence it covered the Sun,
making this a total eclipse.

the Sun and Moon, and the Moon data page displays detailed
information on the Moon's key dates.
Interactive Map
This map shows the visibility of the eclipse.
The shaded area saw the total solar eclipse; however, near the edges of
this area, the eclipse was very short. The bold line shows the centre
of the path, where the eclipse lasted longest.
Use the zoom controls to zoom in and out; hover your mouse over any
point on the centreline to see the time and
duration of the eclipse at that point. You can pan and zoom the map to
see detail for any part of the eclipse path.

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).
