Solar eclipse of July 13, 2018

A partial solar eclipse occurred on Friday, July 13, 2018.[1][2] 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. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth. The moon's penumbra touched a small part of Antarctica, and southern Australia in Tasmania, where the eclipse was observed with a magnitude of about 0.1. The eclipse was also visible in Stewart Island, an island south of New Zealand.[3]

Metonic series

edit

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
