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. 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. [1]
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.
It was preceded two weeks earlier by the total lunar eclipse of December 21, 2010.
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. [2]

A total solar eclipse occurred on March 29, 2006. 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 total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. It was visible from a narrow corridor which traversed half the Earth. The magnitude, that is, the ratio between the apparent sizes of the Moon and that of the Sun, was 1.052, and it was part of Saros 139.
A total solar eclipse took place on December 4, 2002, with a magnitude of 1.0244. 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 total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. It was visible from a narrow corridor in southern Africa, the Indian Ocean and southern Australia. A partial eclipse was seen from the much broader path of the Moon's penumbra, including most of Africa and Australia. During the sunset after the eclipse many observers in Australia saw numerous and unusual forms of a green flash.
An annular solar eclipse occurred at the Moon's descending node of the orbit on October 3, 2005, with a magnitude of 0.958. 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. Occurring only 4.8 days after apogee, the Moon's apparent diameter was smaller. It was visible from a narrow corridor through the Iberian peninsula and Africa and Brazil. A partial eclipse was seen from the much broader path of the Moon's penumbra, including all of Europe, Africa and southwestern Asia. The Sun was 96% covered in a moderate annular eclipse, lasting 4 minutes and 32 seconds and covering a broad path up to 162 km wide. The next solar eclipse in Africa occurred just 6 months later.

An annular solar eclipse occurred on Sunday, June 21, 2020. An annular solar eclipse is a solar eclipse whose presentation looks like a ring, or annulus; it occurs when the Moon's apparent diameter is smaller than the sun's, blocking most, but not all, of the sun's light. In this instance, the moon's apparent diameter was 0.6% smaller than the sun's.
A total solar eclipse took place on Monday, December 14, 2020, when the Moon passed between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. Totality occurred in a narrow path across Earth's surface across parts of the South Pacific Ocean, southern South America, and the South Atlantic Ocean, when the Moon's apparent diameter was larger than the Sun's so all direct sunlight was blocked. The partial solar eclipse was visible over a surrounding region thousands of kilometres wide, including parts of the Pacific Ocean, South America, southwestern Africa, and the Atlantic Ocean. The Moon's apparent diameter was larger than average because the eclipse occurred only 1.8 days after perigee.
An annular solar eclipse occurred on Thursday, June 10, 2021, when the Moon passed between Earth and the Sun, thereby partly obscuring the image of the Sun for a viewer on Earth. During the eclipse, the Moon's apparent diameter was smaller than the Sun's, so it caused the Sun to look like an annulus. The annular eclipse was visible from parts of northeastern Canada, Greenland, the Arctic Ocean, and the Russian Far East, whilst the eclipse appeared partial from a region thousands of kilometres wide, which included northeastern North America, most of Europe, and northern Asia.
A total solar eclipse took place on Saturday, December 4, 2021, when the Moon passed between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. This eclipse was unusual as the path of the total eclipse moved from east to west across West Antarctica, while most eclipse paths move from west to east. This reversal is only possible in polar regions. Its path across Antarctica crossed near Berkner Island, traversed an arc over the continent and passed over Shepard Island.
A total solar eclipse will occur on December 5, 2048. 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 total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.
A hybrid solar eclipse occurred on Thursday, April 20, 2023. A solar eclipse occurs when the Moon passes between Earth and the Sun thereby totally or partly obscuring the Sun for a viewer on Earth. A hybrid solar eclipse is a rare type of solar eclipse that changes its appearance from annular to total and back as the Moon's shadow moves across the Earth's surface. Totality occurs in a narrow path across the surface of the Earth, with the partial solar eclipse visible over a surrounding region thousands of kilometers wide. Hybrid solar eclipses are extremely rare, occurring in only 3.1% of solar eclipses in the 21st century.
The solar eclipse of October 25, 2022, was a partial solar eclipse visible from Europe, the Urals and Western Siberia, Central Asia, Western Asia, South Asia and from the north-east of Africa. The maximal phase of the partial eclipse occurred on the West Siberian Plain in Russia near Nizhnevartovsk, where more than 82% of the Sun was eclipsed by the Moon. In India, the Sun was eclipsed during sunset ranging from 58% in the north and around 2% in the south. From Western Europe it appeared to be around 15-30% eclipsed. It was visible between 08:58 UTC, the greatest point of eclipse occurred at 11:00 UTC and it ended at 13:02 UTC.
