Solar eclipse of April 30, 1957

An annular solar eclipse occurred at the Moon's descending node of orbit on Tuesday, April 30, 1957, with a magnitude of 0.9799. 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. This annular solar eclipse was non-central. Instead, over half of the antumbral shadow fell off into space throughout the eclipse. Gamma had a value of 0.9992. Annularity was visible from northern Soviet Union (today's Russia) and Bear Island, the southernmost island of Svalbard, Norway.

This was the last of 57 umbral eclipses of Solar Saros 118. The 1st was in 947 AD and the 57th was in 1957. The total duration is 1010 years.

While it was an annular solar eclipse, it was a non-central solar eclipse.
