September 1913 lunar eclipse
A total lunar eclipse occurred at the Moon’s ascending node of orbit on Monday, September 15, 1913, with an umbral magnitude of 1.4304. It was a central lunar eclipse, in which part of the Moon passed through the center of the Earth's shadow. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. 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. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring only about 30 minutes after apogee, the Moon's apparent diameter was smaller.
Visibility
The eclipse was completely visible over northeast Asia and Australia, seen rising over much of Asia and east Africa and setting over North America and western South America.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. The first and last eclipse in this sequence is separated by one synodic month.| August 31 Descending node | September 15 Ascending node | September 30 Descending node |
