March 1998 lunar eclipse
A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Friday, March 13, 1998, with an umbral magnitude of −0.3824. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. Occurring about 2.3 days before apogee, the Moon's apparent diameter was smaller.
Visibility
The eclipse was completely visible over much of North America, South America, west Africa and western Europe, seen rising over northwestern North America and the central Pacific Ocean and setting over much of Europe, much of Africa, and west and central Asia.Eclipse details

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 26 Descending node | March 13 Ascending node |
| Total solar eclipse Solar Saros 130 | Penumbral lunar eclipse Lunar Saros 142 |
