Solar eclipse of June 19, 1917

A partial solar eclipse occurred at the Moon's descending node of orbit on Tuesday, June 19, 1917, with a magnitude of 0.4729. 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.
This was the second of four solar eclipses in 1917, with the others occurring on January 23, July 19, and December 14.
A partial eclipse was visible for parts of northern North America, Northern Europe, and North Asia.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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. The first and last eclipse in this sequence is separated by one synodic month.
