A total solar eclipse occurred at the Moon's ascending node of orbit on Tuesday, October 24, 1995,[1] with a magnitude of 1.0213. 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 about 2.7 days before perigee (on October 26, 1995, at 21:00 UTC), the Moon's apparent diameter was larger.[2]

The path of totality went through Iran, Afghanistan, Pakistan, India, southwestern tip of Bangladesh, Burma, Thailand, Cambodia, Vietnam, Spratly Islands, northeastern tip of Sabah of Malaysia, Philippines and Indonesia. A partial eclipse was visible for parts of Northeast Africa, Asia, Australia, and northern Oceania.

Observation

[edit]

India

[edit]

An aerial observation of this eclipse was done over India,[3] when a MiG-25 reconnaissance aircraft of the Indian Air Force was used to take images of this eclipse at an altitude of 25 km.[4]

The Indian Institute of Astrophysics established camps along the path of totality in Rajasthan, Uttar Pradesh, Iradatganj and Diamond Harbour near Kolkata. Astronomers from other institutions and abroad from the Slovakia, Brazil, Russia, Japan and Germany joined IIA at its camps. An IIA team also photographed the eclipse by chasing the Moon’s shadow in an Indian Air Force plane AN-32 from the crew escape hatch on the roof of the cockpit at an altitude of 10,000 feet (3,000 m) above the sea level, which was the first time efforts made by the institute. Doordarshan and All India Radio made live coverages of the eclipse. The eclipse happened to occur on the day of the Diwali.[5]

China

[edit]

Within the Spratly Islands claimed by China, only Cuarteron Reef was controlled by China and lay in the path of totality. Instead of going to the faraway island, The Popular Science Committee of the Chinese Astronomical Society, Beijing Astronomical Society, Beijing Planetarium and Beijing Astronomical Observatory (now incorporated into the National Astronomical Observatories of China) jointly organized observations abroad for the first time. A team of 4 was sent to Sikhio district, Nakhon Ratchasima, Thailand by the Beijing Planetarium, and successfully photographed the whole process of the eclipse, the corona at the greatest eclipse, and the Baily's beads at the 2nd and 3rd contact.[6]

In addition, the Chinese Academy of Sciences, Ministry of Electronics Industry, China Earthquake Administration, State Education Commission (now Ministry of Education) and departments in charge of water conservancy and meteorology conducted joint observations on changes of solar radiation, ionosphere, geomagnetic field, radio and acoustic heavy waves, mainly in the Paracel Islands, Sanya, Haikou and Zhengzhou. From all these places, only a partial solar eclipse was visible instead of a total solar eclipse.[7]

List of major cities in the path of totality

Phil Whitaker's prize-winning debut novel Eclipse of the Sun published in 1997 and set in India has at its centre a dramatic attempt to organize a public viewing of the eclipse.

Eclipse season

[edit]

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

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.[10]

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.[11]

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.

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.

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.
