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]
