March 1997 lunar eclipse
Template:Short description Template:Infobox lunar eclipse A partial lunar eclipse occurred at the Moon’s ascending node of orbit on Monday, March 24, 1997,[1] with an umbral magnitude of 0.9195. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 3.2 days after apogee (on March 20, 1997, at 23:40 UTC), the Moon's apparent diameter was smaller.[2]
This lunar eclipse was the third of an almost tetrad, with the others being on April 4, 1996 (total); September 27, 1996 (total); and September 16, 1997 (total).
This was the last of the first set of partial eclipses in Lunar Saros 132.
Visibility
The eclipse was completely visible over much of North America and South America, seen rising over western North America and the central Pacific Ocean and setting over Africa, Europe, and west and central Asia.[3]

Eclipse season
Script error: No such module "Labelled list hatnote". This 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.

Saros 132
This eclipse is a part of Saros series 132, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on May 12, 1492. It contains partial eclipses from August 16, 1636 through March 24, 1997; total eclipses from April 4, 2015 through August 2, 2213; and a second set of partial eclipses from August 13, 2231 through November 30, 2411. The series ends at member 71 as a penumbral eclipse on June 26, 2754.
The longest duration of totality will be produced by member 36 at 106 minutes, 6 seconds on June 9, 2123. All eclipses in this series occur at the Moon’s ascending node of orbit.[5]

Eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

Inex series
This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
