A total eclipse of the Sun occurs on Sunday 4 August, 2176 UT, with maximum eclipse at 22:59 UT. A dramatic total eclipse will plunge the Sun into darkness for 3 minutes and 40 seconds at maximum, creating an amazing spectacle for observers in a path up to 136 km wide.
The total eclipse lasts for 3 minutes and 40 seconds.
Maximum eclipse is at 22:59:29 UT.
During this eclipse the Sun will be 0.525° in apparent
diameter, 1.4% smaller than average. The Moon will be just 3 days past perigee, making it relatively large.
At the start and end of the eclipse the Moon
will be 0.537°, and at maximum eclipse 0.546°,
which is 2.7% larger than average; hence it will cover the Sun,
making this a total 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.

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).
