Solar eclipse of June 1, 2087

A partial solar eclipse will occur at the Moon's descending node of orbit on Sunday, June 1, 2087,^[1] with a magnitude of 0.2146. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

Eclipse season

See also: Eclipse cycle

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.

Solar eclipses of 2083–2087

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.^[3]

The partial solar eclipses on February 16, 2083 and August 13, 2083 occur in the previous lunar year eclipse set, and the partial solar eclipses on May 2, 2087 and October 26, 2087 occur in the next lunar year eclipse set.

Saros 158

This eclipse is a part of Saros series 158, repeating every 18 years, 11 days, and containing 70 events. The series will start with a partial solar eclipse on May 20, 2069. It contains total eclipses from August 5, 2195 through August 13, 2808; hybrid eclipses on August 24, 2826 and September 3, 2844; and annular eclipses from September 15, 2862 through February 27, 3133. The series ends at member 70 as a partial eclipse on June 16, 3313. Its 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.

The longest duration of totality will be produced by member 10 at 4 minutes, 43 seconds on August 28, 2231, and the longest duration of annularity will be produced by member 57 at 6 minutes, 7 seconds on January 25, 3079. All eclipses in this series occur at the Moon’s descending node of orbit.^[4]

Series members 1–8 occur between 2069 and 2200:

Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's descending node.

Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic 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.

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.
