A total solar eclipse occurred on May 30, 1965. 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 northwestern Northland Region in New Zealand on May 31 (Monday), and Manuae in Cook Islands, Manuae and Motu One in French Polynesia, and Peru on May 30 (Sunday).

As most of the eclipse's path was over open ocean, a prolonged observation was made by a jet transport; flying parallel to the path of the eclipse at 587 mph (945 km/h), this gave scientists what was at the time the "longest probe in man's history into the conditions of a solar eclipse", for nearly ten minutes. The expedition involved scientists from NASA, Belgium, Italy, the Netherlands, and Switzerland; in total, 30 researchers and 13 separate research projects were represented on the plane. ^{[1] [2] [3]} The plane, operated by NASA, took off from Hilo, Hawaii, and met up with the path of the eclipse approximately 1,000 mi (1,600 km) south of there. ^[4] While mostly invisible from land, some ground-based observers in an 85-mile-wide strip of northern New Zealand were able to clearly view the event. ^[4]

Solar eclipses of 1964–1967

This eclipse is a member of a 1964–1967 series at alternating nodes every 6 synodic months.

Note: Partial solar eclipses on January 14, 1964 and July 9, 1964 belong to the previous lunar year set.

Saros 127

It is a part of Saros cycle 127, repeating every 18 years, 11 days, containing 82 events. The series started with partial solar eclipse on October 10, 991 AD. It contains total eclipses from May 14, 1352 through August 15, 2091. There are no annular eclipses in this series. The series ends at member 82 as a partial eclipse on March 21, 2452. The longest duration of totality was 5 minutes, 40 seconds on August 30, 1532. All eclipses in this series occurs at the Moon’s ascending node. ^[5]

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.

Inex series members between 1901 and 2100:
July 10, 1907 (Saros 125)	June 19, 1936 (Saros 126)	May 30, 1965 (Saros 127)
May 10, 1994 (Saros 128)	April 20, 2023 (Saros 129)	March 30, 2052 (Saros 130)
March 10, 2081 (Saros 131)

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 ascending node.
