The solar eclipse of January 15, 2010, was an annular eclipse of the Sun with a magnitude of 0.9190. Template:Annular solar eclipse summary

It was the longest annular solar eclipse of the millennium,[1] and the longest until December 23, 3043, with a maximum length of 11 mins and 7.8 seconds. (The solar eclipse of January 4, 1992, was longer, at 11 minutes, 41 seconds, occurring in the middle of the Pacific Ocean.)[2]

The eclipse was visible as only partial eclipse in much of Africa, Eastern Europe, the Middle East and Asia. It was seen as annular eclipse within a narrow stretch of 300 km (190 mi) width across Central Africa, Maldives, South Kerala (India), South Tamil Nadu (India), Sri Lanka and parts of Bangladesh, Burma and China.

Visibility of the eclipse

The eclipse starts at the Central African Republic, traverses Cameroon, DR Congo and Uganda, passes through Nairobi, Kenya, enters the Indian Ocean and reaches its greatest eclipse.

After that it enters Maldives, where it would be the longest on land with 10.8 minutes of viewing. This makes the tiny islands of Maldives the best spot for viewing this eclipse from land. The annular eclipse at Malé, the capital city of Maldives, starts at 12:20:20 hrs and ends 12:30:06 hrs Maldives local time (UTC+5). This is also the longest duration of any city having an international airport in the eclipse track.[3]

At approximately 13:20 IST, the annular solar eclipse entered India at Thiruvananthapuram (Trivandrum), Kerala and exited India at Rameswaram, Tamil Nadu. The eclipse is viewable for 10.4 minutes in India. After Rameswaram, it enters Sri Lanka at Delft Island, exits at Jaffna in Sri Lanka, crosses the Bay of Bengal and re-enters India in Mizorum.

Thiruvananthapuram city, which is the entry point of the eclipse in India, is equipped with telescopes and announced facilities for the public to view the eclipse.[4] Vikram Sarabhai Space Centre, situated in Trivandrum, is analysing the atmospheric-ionospheric parameters during the eclipse.[5] Many scientists have camped in the city to witness and study the eclipse.[6]

Dhanushkodi, which falls on the central line of the eclipse, was a good place to view the eclipse. The northern most limit of shadow in India is Cuddalore, Neyveli, Erode, Kodaikanal, Madurai. Other prime viewing locations in Tamil Nadu include Thoothukudi and Cape Comorin, 22 km north of the center line. The only means of reaching Dhanushkodi or Kodandaramar Temple is by ST bus or automobile from Rameswaram. Reaching Dhanushkodi involves traveling in fish carts or 4x4 SUVs, after the end of the road. Governmental permission is required for entering the Dhanushkodi ruins from the coast guard post as that area is 10 km from the Sri Lankan coast. The centre line passes some 2 km east of the Kodandaramar Temple. The exact location of the line is between the NH end and the Dhanushkodi ruins. Dhanushkodi is about 2 km east of the central line. The degree difference is about 0.2 between the central line – Kodandaramar Temple and Dhanushkodi ruins vice versa. Dhanushkodi is about 5 km from the Kodandaramar Temple.

After South Asia, annularity passed Myanmar and China before leaving the Earth.

Saros 141

This eclipse is a part of Saros series 141, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on May 19, 1613. It contains annular eclipses from August 4, 1739 through October 14, 2640. There are no hybrid or total eclipses in this set. The series ends at member 70 as a partial eclipse on June 13, 2857. 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 annularity was produced by member 20 at 12 minutes, 9 seconds on December 14, 1955. All eclipses in this series occur at the Moon’s ascending node of orbit.[7]

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.
