Solar eclipse of July 10, 1972
A total solar eclipse occurred on Monday, July 10, 1972. 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. Occurring only 2.9 days after perigee (Perigee on July 7, 1972), the Moon's diameter was relatively large.
It was visible as a total eclipse along a path of totality that began in Sea of Okhotsk and traversed the far eastern portions of the Soviet Union (which now belongs to Russia) on July 11 local time, northern Alaska in the United States, Northern Canada, eastern Quebec and the Canadian Maritimes on July 10 local time. A partial eclipse was visible over Siberia, Canada and the northern and eastern United States.
The eclipse was mostly seen on July 10, 1972, except for the Asian part of Soviet Union and Japanese island Hokkaido, where either a partial or a total eclipse was seen on July 11 local time, and part of the Soviet Union along the coast of Kara Sea, where a partial eclipse started on July 10, passing midnight and ended on July 11 due to the midnight sun.
Observations
A team of the Academy of Sciences of the Soviet Union observed the total solar eclipse in Russkaya Koshka, Magadan Oblast (now separated into Chukotka Autonomous Okrug) on the coast of Gulf of Anadyr. The weather condition was clear, and the team successfully took images of the corona and made polarization observations to study its structure and physical characteristics.[1] In Nova Scotia, Canada, the eclipse was clouded out and could not be observed. Besides that, 850 passengers boarded a cruise ship from New York City and saw a total eclipse successfully in North Atlantic Ocean. Many scientists also boarded the ship and did research, and some also gave classes in meteorology, oceanography, etc., which almost all passengers attended.[2][3]
"You're So Vain"
The eclipse is referenced in the lyrics of Carly Simon's 1972 hit song "You're So Vain." The subject of the song, after witnessing his racehorse win "naturally" at the Saratoga Race Course, flies his Learjet to Nova Scotia to see the eclipse; Simon uses the two phenomena as examples of how the subject seems to be "where (he) should be all the time." Simon released the song four months after the eclipse.[4]

Solar eclipses of 1971–1974
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.[5]
Note: Partial solar eclipses on February 25, 1971 and August 20, 1971 occur in the next lunar year set.

Saros 126
It is a part of Saros cycle 126, repeating every 18 years, 11 days, containing 72 events. The series started with partial solar eclipse on March 10, 1179. It contains annular eclipses from June 4, 1323 through April 4, 1810, hybrid eclipses from April 14, 1828 through May 6, 1864 and total eclipses from May 17, 1882 through August 23, 2044. The series ends at member 72 as a partial eclipse on May 3, 2459. The longest duration of central eclipse (annular or total) was 6 minutes, 30 seconds of annularity on June 26, 1359. The longest duration of totality was 2 minutes, 36 seconds on July 10, 1972. All eclipses in this series occurs at the Moon’s descending node.

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.
