A total lunar eclipse occurred on February 20 and February 21, 2008. It was visible in the eastern evening sky on February 20 for all of North and South America, and on February 21 in the predawn western sky from most of Africa and Europe. Greatest Eclipse occurring on Thursday, February 21, 2008, at 03:26:03 UTC, totality lasting 49 minutes and 45.6 seconds.

Occurring 7.1 days after perigee (Perigee on February 14, 2008) and 6.9 days before apogee (Apogee on February 28, 2008), the Moon's apparent diameter was near the average diameter.

The total lunar eclipse was the first of the two lunar eclipses in 2008, with the second, the August 16, 2008 event being partial. [1] The next total lunar eclipse occurred on December 21, 2010. The tables below contain detailed predictions and additional information on the Total Lunar Eclipse of 21 February 2008.

The Moon's apparent diameter was 26.2 arcseconds larger than the August 16, 2008 partial lunar eclipse.

These simulated views of the earth from the center of the moon during the lunar eclipse show where the eclipse is visible on earth.

The penumbral eclipse began at 00:35 UTC (February 21), and ended at 6:17. A partial eclipse existed from 1:43 until 3:00, followed by 51 minutes of totality (3:00 - 3:51), and then partial again from 3:51 until 5:09. (For local times, see Timing.)

It is possible to mistake the appearance of partial eclipse as the Moon being in a different phase, but the shadow from the eclipse changes much more rapidly. [2]

The bright star Regulus of Leo and the planet Saturn were prominent very near the Moon during the total eclipse portion. Shortly before the eclipse began, Regulus was occulted by the Moon in parts of the far Southern Atlantic Ocean and Antarctica.

Saros series

This lunar eclipse is part of series 133 of the Saros cycle, which repeats every 18 years and 11 days. Series 133 runs from the year 1557 until 2819. The previous eclipse of this series occurred on February 9, 1990, and the next will occur on March 3, 2026.

It is the 6th of 21 total lunar eclipses in series 133. The first was on December 28, 1917. The last (21st) will be on August 3, 2278. The longest two occurrences of this series (14th and 15th) will last for a total of 1 hour and 42 minutes on May 18, 2152, and May 30, 2170. Solar saros 140 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Lunar saros series 133, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 54 umbral lunar eclipses (33 partial lunar eclipses and 21 total lunar eclipses).

GreatestFirst

The greatest eclipse of the series will occur on 2170 May 30, lasting 102 minutes.

Metonic cycle (19 years)

This is the fourth of five Metonic lunar eclipses.

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the earth's shadow will in nearly the same location relative to the background stars.

<span class="mw-page-title-main">Solar eclipse of August 1, 2008</span> 21st-century total solar eclipse

A total solar eclipse occurred at the Moon's descending node of the orbit on August 1, 2008. 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 had a magnitude of 1.0394 that was visible from a narrow corridor through northern Canada (Nunavut), Greenland, central Russia, eastern Kazakhstan, western Mongolia and China. Occurring north of the arctic circle, it belonged to the so-called midnight sun eclipses. The largest city in the path of the eclipse was Novosibirsk in Russia. Occurring only 2.5 days after perigee, the Moon's apparent diameter was larger than average.

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.
