A total lunar eclipse will occur at the Moon’s ascending node of orbit on Friday, July 17, 2065,[1] with an umbral magnitude of 1.6628. It will be a central lunar eclipse, in which part of the Moon will pass 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 about 4.2 days after perigee (on July 14, 2065, at 13:50 UTC), the Moon's apparent diameter will be larger.[2]
Visibility
The eclipse will be completely visible over south and east Asia, Australia, and Antarctica, seen rising over much of Africa, Europe, and west and central Asia and setting over northeast Asia and the central Pacific Ocean.[3]
Eclipse details
Shown below is a table displaying details about this particular lunar eclipse. It describes various parameters pertaining to this eclipse.[4]
| Parameter | Value |
|---|---|
| Penumbral magnitude | 2.59069 |
| Umbral magnitude | 1.61381 |
| Gamma | −0.14023 |

| Sun declination | +20°59'34.9" |
| Sun semi-diameter | 15'44.3" |
| Sun equatorial horizontal parallax | 08.7" |
| Moon right ascension | 19h50m58.2s |
| Moon declination | -21°07'32.3" |

| Moon equatorial horizontal parallax | 0°59'07.5" |
| ΔT | 96.0 s |
Eclipse season
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. The first and last eclipse in this sequence is separated by one synodic month.

Lunar eclipses of 2064–2067
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 eclipses on May 28, 2067 and November 21, 2067 occur in the next lunar year eclipse set.

Half-Saros cycle
A 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 annular solar eclipses of Solar Saros 137.
