Solar eclipse of May 19, 1985
A partial solar eclipse occurred at the Moon's ascending node of orbit between Sunday, May 19 and Monday, May 20, 1985, with a magnitude of 0.8406. 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.
A partial eclipse was visible near sunrise on May 20 over Japan and northeast Russia and ended on May 19 over Alaska and near sunset over northern Canada and Greenland.

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.| May 4 Descending node | May 19 Ascending node |
| Total lunar eclipse Lunar Saros 121 | Partial solar eclipse Solar Saros 147 |
