A partial solar eclipse occurred on July 13, 2018. 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. Part of the Moon's shadow fell near the South Pole, so partial coverage of the Sun was visible in parts of southern Australia, such as Melbourne and Geelong in Victoria, Mount Gambier in South Australia, and Hobart and Launceston in Tasmania, with highest magnitude of about 0.1. The eclipse was also visible in Stewart Island in the far south of New Zealand.[1]

Partial Solar Eclipse on Friday the 13th

This is the first partial solar eclipse on Friday the 13th since December 1974 and the last until September 2080. The next solar eclipse on Friday 13 will be a total eclipse in June 2132.

Metonic series

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.
