A partial solar eclipse will occur at the Moon's descending node of orbit on Friday, October 24, 2098, with a magnitude of 0.0056. 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.

This minor eclipse is the first solar eclipse of Saros cycle 164. It is the shallowest solar eclipse of the 21st century; at best, in a remote location within the Southern Ocean the moon will block out 0.56% of the sun's diameter with the sun barely above the horizon. Gamma is equal to −1.5407, which is also farther from zero than any other solar eclipse in the century. The eclipse is not listed by some sources.[1] There will not be a shallower partial eclipse until August 23, 2883.

Eclipse season
editThis 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 2094–2098
editThis 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 solar eclipses on January 16, 2094 (total) and July 12, 2094 (partial) occur in the previous lunar year eclipse set, and the partial solar eclipses on April 1, 2098 and September 25, 2098 occur in the next lunar year eclipse set.

Saros 164
editThis eclipse is a part of Saros series 164, repeating every 18 years, 11 days, and containing 80 events. The series will start with a partial solar eclipse on October 24, 2098. It contains total eclipses from June 1, 2459 through June 20, 3090; hybrid eclipses from July 1, 3108 through August 3, 3162; and annular eclipses from August 13, 3180 through September 4, 3216. The series ends at member 80 as a partial eclipse on March 10, 3523. 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 was produced by member 26 at 6 minutes, 30 seconds on July 25, 2549, and the longest duration of annularity was produced by member 63 at 1 minutes, 21 seconds on September 4, 3216. All eclipses in this series occur at the Moon’s descending node of orbit.[4]

Metonic series
editThe 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
editThis 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.
The partial solar eclipse on October 24, 2098 (part of Saros 164) is also a part of this series but is not included in the table below.
