A partial solar eclipse occurred at the Moon's ascending node of orbit on Monday, October 2, 1978, with a magnitude of 0.6905. 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. The eclipse is a part of the 153 saros cycle. Its the 7th eclipse of the saros cycle. The solar eclipse was visible in most of Asia Except northern Asia, Northeastern Europe, tiny northern part of Oceania, and tiny parts of Guam and other American islands

Solar eclipses of 1975–1978
[edit]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.[1]

Saros 153
[edit]This eclipse is a part of Saros series 153, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on July 28, 1870. It contains annular eclipses from December 17, 2104 through May 26, 2970. There are no hybrid or total eclipses in this set. The series ends at member 70 as a partial eclipse on August 22, 3114. 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 annularity will be produced by member 38 at 7 minutes, 1 seconds on September 5, 2537. All eclipses in this series occur at the Moon’s ascending node of orbit.[2]

Tritos series
[edit]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.
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.

Metonic series
[edit]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 ascending node.
