During this eclipse the Sun was 0.526° in apparent diameter, 1.3% smaller than average. The Moon was just 2 days past apogee, making it extremely small. At maximum eclipse it was 0.494° in apparent diameter, which is 7.0% smaller than average; this was not large enough to cover the Sun, which is why this was an annular eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon.
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:||01:46:20 UT|
|Annular eclipse began:||03:44:53 UT|
|Maximum eclipse:||04:08:21 UT|
|Annular eclipse ended:||04:31:28 UT|
|Partial eclipse ended:||06:30:05 UT|
The next eclipse in the triple-Saros series will happen on Jul 1, 2057, but will not be visible in Britain. However, two eclipses later in the same Saros series, an eclipse is visible in central Britain on Jul 23 2093.
An annular eclipse — the first central (ie. not partial) eclipse in its series — covers the top of the Earth, and partly misses it entirely. Large parts of Greenland will see the eclipse, and the centre line passes over Iceland. For the UK, it will be seen in most of the Highlands, including Inverness, the Orkneys, Shetlands, and Lewis, at around dawn. The rest of the UK will see the Sun rise partially eclipsed.
This map shows the visibility of the eclipse. The shaded area saw the annular 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.
This map sourced from NASA's Eclipse Web Site shows the visibility of the annular solar eclipse. It also shows the broader area in which a partial eclipse was seen. (Click on it for the full-sized version.)

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). The statistics page has information on the ranges of sizes of the Sun and Moon.
