}} with a magnitude of 0.9868. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. The Moon's apparent diameter was near the average diameter because it occurred 6.2 days after perigee (on April 23, 2014, at 1:20 UTC) and 7.2 days before apogee (on May 6, 2014, at 11:20 UTC).{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2014&n=136|publisher=timeanddate|access-date=12 August 2024}}
This eclipse's gamma value was closer to 1 than any other eclipse from 2000 B.C. to 3000 A.D. This means the center of the Moon's shadow passed almost exactly at the surface of the Earth, barely missing the Antarctic continent by a few kilometers, but an annular eclipse was visible from a small part of Antarctica, and a partial eclipse was visible from parts of Antarctica and Australia.

Eclipse season
{{See also|Eclipse cycle}}
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
