The solar eclipse of January 4, 2011 was a partial eclipse of the Sun that was visible after sunrise over most of Europe, northwestern and South Asia.^[1]^[2] It ended at sunset over eastern Asia. It was visible as a minor partial eclipse over northern Africa and the Arabian peninsula. The eclipse belonged to Saros 151 and was number 14 of 72 eclipses in the series.

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.

Solar eclipses 2008–2011[edit]

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.^[4]

Partial solar eclipses on June 1, 2011, and November 25, 2011, occur on the next lunar year eclipse set.

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.
