A total solar eclipse occurred at the Moon's ascending node of orbit on Friday, October 2, 1959, with a magnitude of 1.0325. 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 total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Totality was visible from northeastern Massachusetts and the southern tip of New Hampshire in the United States, Canary Islands, Morocco, Spanish Sahara (today's West Sahara) including the capital city Laayoune, French Mauritania (today's Mauritania), Mali Federation (part now belonging to Mali), French Niger (today's Niger), British Nigeria (today's Nigeria), British Cameroons and French Cameroons (now belonging to Cameroon), French Chad (today's Chad) including the capital city Fort-Lamy, French Central Africa (today's Central African Republic), Sudan (part of the path of totality is now in South Sudan), Ethiopia, and the Trust Territory of Somaliland (today's Somalia).
Observations[edit]
Totality began over Boston, Massachusetts at sunrise. Viewing the eclipse was rained out, but it was reported that the brightening of the sky after the eclipse was a startling and impressive sight.[1] A few photographers captured the eclipse from airplanes above the clouds, and a multiple exposure was made atop the R. C. A. building in New York City.[2] The next total eclipse over Boston, the solar eclipse of May 1, 2079, will also be a sunrise event.[3]
The event was also observed at the Canarian Island of Fuerteventura by a team of Dutch astronomers of the university of Utrecht and Amsterdam.[4][5]
Maurice Allais, a French polymath, reported the alleged anomalous behavior of pendulums or gravimeters, later named as Allais effect. He first reported the effect after observing the solar eclipse of June 30, 1954, and reported another observation of the effect during this solar eclipse using the paraconical pendulum he invented.[6]

Solar eclipses of 1957–1960[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.[7]

Saros 143[edit]
This eclipse is a part of Saros series 143, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on March 7, 1617. It contains total eclipses from June 24, 1797 through October 24, 1995; hybrid eclipses from November 3, 2013 through December 6, 2067; and annular eclipses from December 16, 2085 through September 16, 2536. The series ends at member 72 as a partial eclipse on April 23, 2897. 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 16 at 3 minutes, 50 seconds on August 19, 1887, and the longest duration of annularity will be produced by member 51 at 4 minutes, 54 seconds on September 6, 2518. All eclipses in this series occur at the Moon’s ascending node of orbit.[8]

Inex series[edit]
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.

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.

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).
