A totallunar eclipse will occur at the Moon’sascending node of orbit on Sunday, July 7, 2047,[1] with an umbralmagnitude of 1.7529. It will be acentral lunar eclipse, in which part of theMoon will pass through thecenter of theEarth's shadow. A lunar eclipse occurs when theMoon moves into theEarth'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 asolar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on thenight 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'sshadow is smaller. Occurring about 3.4 days afterperigee (on July 4, 2047, at 0:55 UTC), the Moon's apparent diameter will be larger.[2]
Totality will last 100 minutes 49 seconds, the second longest for thisSaros series.
The eclipse will be completely visible over easternAustralia,Antarctica, and the central and easternPacific Ocean, seen rising overeast Asia and western Australia and setting overNorth andSouth America.[3]

This eclipse is part of aneclipse 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 afortnight. The first and last eclipse in this sequence is separated by onesynodic month.

This eclipse is a member of asemester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternatingnodes of the Moon's orbit.[5]
The penumbral lunar eclipses onMay 17, 2049 andNovember 9, 2049 occur in the next lunar year eclipse set.

This eclipse is a part ofSaros series 130, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on June 10, 1416. It contains partial eclipses from September 4, 1560 throughApril 12, 1903; total eclipses fromApril 22, 1921 through September 11, 2155; and a second set of partial eclipses from September 21, 2173 through May 10, 2552. The series ends at member 71 as a penumbral eclipse on July 26, 2678.
The longest duration of totality will be produced by member 35 at 101 minutes, 53 seconds onJune 26, 2029. All eclipses in this series occur at the Moon’sascending node of orbit.[6]

This eclipse is a part of atritos cycle, repeating at alternating nodes every 135synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
