Solar eclipse of March 7, 1989
A partial solar eclipse occurred at the Moon's ascending node of orbit on Tuesday, March 7, 1989, with a magnitude of 0.8268. 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 for parts of Hawaii, Alaska, Canada, the western and central United States, northwest Mexico, 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.| February 20 Descending node | March 7 Ascending node |
| Total lunar eclipse Lunar Saros 123 | Partial solar eclipse Solar Saros 149 |
