A total solar eclipse occurred at the Moon's descending node of the orbit on February 16, 1980. 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. The path of totality crossed central Africa, southern India, and into China at sunset. The southern part of Mount Kilimanjaro, the highest mountain in Africa, also lies in the path of totality. Occurring only about 24 hours before perigee (Perigee on February 17, 1980), the Moon's apparent diameter was larger. This was a Supermoon Total Solar Eclipse because the Moon was just a day before perigee.[ citation needed ]
This was the third total solar eclipse visible from mainland India excluding the Andaman and Nicobar Islands in the 20th century. However, most of the path of totality of the solar eclipse of August 21, 1914 in British India now belongs to Pakistan, and the only place within the path of totality of the solar eclipse of June 30, 1954 in India was in the Thar Desert where a total eclipse occurred right before sunset. Therefore, this was actually the first total solar eclipse visible from India with good observation conditions since January 22, 1898 [1] .
The Indian Institute of Astrophysics established two camps at Hosur near Hubli and at Jawalagera near Raichur, analyzing the chromospheric and coronal radiation. Observation teams from Czechoslovakia and Yugoslavia also made observations nearby [2] . The Astronomical Institute of Slovak Academy of Sciences also sent a team of 7 people near Jawalagera. The weather condition was good and the team took images of the corona [3] .
Being the first total solar eclipse visible from China after the Cultural Revolution, this eclipse offered much better conditions for observations, compared with the solar eclipse of September 22, 1968, the previous total one visible from China. Although both occurred before sunset with a low solar zenith angle in China, the maximum duration of totality within China was more than 1 minute and 40 seconds for this eclipse, and less than half a minute for the one in 1968.
The Chinese Academy of Sciences held a solar physics conference in Kunming in April 1975, proposing to form a joint observation of the eclipse. In March 1976, a field trip to select the location of observation was conducted. A total of 31 aspects of observations were organized, including solar optical and radio observations, ionosphere, Earth's magnetic field and gravitational field measurements. The meteorological department also studied weather changes during the eclipse. Optical observations in China were mainly conducted at Yingpan Mountain in Ruili County (now Ruili City), Yunnan, while radio observations were at Yunnan Astronomical Observatory in Fenghuang Mountain, Kunming. In addition, Shanghai Scientific and Educational Film Studio made a documentary on the entire process of the observation [4] [5] .
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. [6] There were 8 solar eclipses between February 26, 1979 and July 20, 1982. Were there: February 26, 1979 (total solar eclipse, 0.8 days after perigee, 103.9%, 0.89811 gamma, saros 120), August 22, 1979 (small annular solar eclipse, 0.6 days before apogee, 93.3%, −0.96319 gamma, saros 125), February 16, 1980 (total solar eclipse, 1 day before perigee, 104.3%, 0.22244 gamma, saros 130), August 10, 1980 (large annular solar eclipse, 5 days before apogee, 97.3%, −0.19154 gamma, saros 135), February 4, 1981 (large annular solar eclipse, 4 days before perigee, 99.4%, −0.48375 gamma, saros 140), July 31, 1981 (total solar eclipse, 3.8 days after perigee, 102.6%, 0.57917 gamma, saros 145), January 25, 1982 (moderate partial solar eclipse, 4.7 days after apogee, 56.6%, −1.23110 gamma, saros 150) and July 20, 1982 (small partial solar eclipse, 0.9 days after perigee, 46.4%, 1.28859 gamma, saros 155).

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.

It was visible from a narrow corridor in southern Africa, the Indian Ocean and southern Australia. A partial eclipse was seen from the much broader path of the Moon's penumbra, including most of Africa and Australia. During the sunset after the eclipse many observers in Australia saw numerous and unusual forms of a green flash.

A total solar eclipse will occur at the Moon's descending node of the orbit on Wednesday, August 12, 2026, two days past perigee, in parts of North America and Europe. The total eclipse will pass over the Arctic, Greenland, Iceland, Atlantic Ocean and northern Spain.
