Solar eclipse of January 15, 2010
An annular solar eclipse occurred at the Moon's ascending node of the orbit on January 15, 2010, with a magnitude of 0.91903. 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, and the longest until December 23, 3043, with the length of maximum eclipse of 11 minutes, 7.8 seconds, and the longest duration of 11 minutes, 10.7 seconds. This is about 4 minutes longer than total solar eclipses could ever get.

A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially. Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to the plane of Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years.
A total solar eclipse occurs when the Moon completely covers the Sun's disk, as seen in this solar eclipse. Solar prominences can be seen along the limb (in red) as well as extensively the coronal and partly the radiating coronal streamers.
An annular solar eclipse occurs when the Moon is too far away to completely cover the Sun's disk (October 14, 2023).
During a partial solar eclipse, the Moon blocks only part of the Sun's disk (October 25, 2022).
