A total eclipse of the Sun occurred on Saturday 1 October, 1921 UT (18 Sep, 1921 Old Style), with maximum eclipse at 12:35 UT. The Sun was darkened for 1 minute and 52 seconds by a dramatic total eclipse covering a very broad path, 291 km wide at maximum. This was a sight worth seeing.
The total eclipse lasted for 1 minute and 52 seconds.
Maximum eclipse was at 12:35:36 UT.
During this eclipse the Sun was 0.533° in apparent
diameter, around average. The Moon was just 2 days past perigee, making it fairly large.
At the start and end of the eclipse the Moon
was 0.545°, and at maximum eclipse 0.548°,
which is 3.3% 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.
The interactive map is currently not available.

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).
