Summary
A partial solar eclipse occurred on May 19–20, 1985. 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. It was visible near sunrise on May 20 over Japan and northeast Russia, and ending at sunset on May 19 over north Canada and Greenland. May 19 is the 139th (140th in leap years) day of the year in Gregorian Calendar. There are 226 days remaining until the end of the year.

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.
