September 1996 lunar eclipse
A total lunar eclipse occurred at the Moon’s descending node of orbit on Friday, September 27, 1996, with an umbral magnitude of 1.2395. 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 about 2.2 days after perigee, the Moon's apparent diameter was larger.
This lunar eclipse was the second of an almost tetrad, with the others being on April 4, 1996 ; March 24, 1997 ; and September 16, 1997.
Visibility
The eclipse was completely visible over eastern North America, South America, western Europe, and west Africa, seen rising over western North America and the eastern and central Pacific Ocean and setting over eastern Europe, central and east Africa, and the western half of Asia.Mid-infrared image of the Moon
During its totality, the Midcourse Space Experiment satellite's SPIRIT-III instrument took the image of the Moon in mid-infrared. At these wavelengths, MSX was able to characterize the thermal distribution of the lunar surface during the eclipse. The brightest regions are the warmest, and the darkest areas are the coolest. The well-known crater Tycho is the bright object to the south of center. Numerous other craters are also seen as bright spots, indicating that their temperature is higher than in the surrounding dark mare.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.| September 27 Descending node | October 12 Ascending node |
| Total lunar eclipse Lunar Saros 127 | Partial solar eclipse Solar Saros 153 |
