Greatest eclipse occurred at 08:51 UTC in northern Sweden where the eclipse in the horizon had a magnitude of 0.858. At that time, the axis of the Moon's shadow passed a mere 510 km above Earth's surface.[3]

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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth. This was the first of four partial solar eclipses in 2011, with the others occurring on June 1, 2011, July 1, 2011, and November 25, 2011.

It also precedes the two total lunar eclipses occurring on June 15, 2011 and December 10, 2011.
