March 1998 lunar eclipse
A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Friday, March 13, 1998,[1] 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 (on March 15, 1998, at 12:40 UTC), the Moon's apparent diameter was smaller.[2] VisibilityThe 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.[3] Eclipse detailsShown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]
Eclipse seasonThis eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) 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.

Lunar eclipses of 1995–1998This is the last of four lunar year eclipses at the ascending node of the Moon's orbit. This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[5] The penumbral lunar eclipse on August 8, 1998 occurs in the next lunar year eclipse set.
Half-Saros cycleA lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[6] This lunar eclipse is related to two partial solar eclipses of Solar Saros 149.
