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

It was the longest annular solar eclipse of the millennium,[1] and the longest until December 23, 3043, with a maximum length of 11 minutes, 7.8 seconds. This is about 4 minutes longer than total solar eclipses could ever get. (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 a partial eclipse in much of Africa, Eastern Europe, the Middle East and Asia. It was seen as an 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[edit]

January 15, 2010's sunrise in Central Africa

The eclipse started in the Central African Republic, traversed Cameroon, DR Congo and Uganda, passed through Nairobi, Kenya, and passed over the Indian Ocean, where it reached its greatest visibility. It then entered Maldives, where it was the longest on land with 10.8 viewable minutes. The annular eclipse at Malé, the capital city of Maldives, started at 12:20:20 and ended at 12:30:06 Maldives local time (UTC+5). This was also the longest duration of any eclipse with an international airport in its 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 was viewable for 10.4 minutes in India. After Rameswaram, it entered Sri Lanka at Delft Island, exited at Jaffna in Sri Lanka, crossed the Bay of Bengal and re-entered India in Mizoram.

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

At Rameswaram, the sunrise was not visible due to thick clouds, but it started getting clear at around 9 AM local time and became almost totally clear by the time the eclipse began. The sky had a thin layer of cirrus clouds till 2:30PM. Among the eclipse-watchers was Sky Watchers' Association of North Bengal (SWAN) from Siliguri at the foothills of West Bengal and Tamil Nadu Astronomical Association.

Dhanushkodi, which falls on the central line of the eclipse, was a good place to view the eclipse. The northernmost limit of shadow in India was Cuddalore, Neyveli, Erode, Kodaikanal, and Madurai. Other prime viewing locations in Tamil Nadu include Thoothukudi and Cape Comorin, 22 km north of the center line. 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 – with 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.
