Summary
An annular solar eclipse occurred on March 7, 1951, with a magnitude of 0.9896. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible from New Zealand on March 8 (Thursday), and northern Costa Rica, Nicaragua, and San Andrés Island in Colombia on March 7 (Wednesday).

Broadcast edit
This was the first solar eclipse in the world broadcast live on television. American stations such as WCBS-TV, WNET, and NBC News broadcast it live. The path of annularity did not pass the United States of America, and only a partial solar eclipse was visible from the southeastern half of the country. For example, in New York City, a partial solar eclipse occurred right before the sunset, whose gratitude (ratio of diameter covered by the moon) was only 17%, meaning only 8% of the total disk area was covered at the peak of the eclipse. The curator of the Hayden Planetarium in New York also asked "don’t get people too excited about it" in an interview with The New York Times, but many TV stations still incorporated the solar eclipse into their regular afternoon schedule and also some new TV technology was inaugurated.[1]

Saros 129 edit
It is a part of Saros cycle 129, repeating every 18 years, 11 days, containing 80 events. The series started with partial solar eclipse on October 3, 1103. It contains annular eclipses on May 6, 1464 through March 18, 1969, hybrid eclipses from March 29, 1987 through April 20, 2023 and total eclipses from April 30, 2041 through July 26, 2185. The series ends at member 80 as a partial eclipse on February 21, 2528. The longest duration of totality was 3 minutes, 43 seconds on June 25, 2131 . All eclipses in this series occurs at the Moon’s ascending node.[3]

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.
