Eclipses

A solar eclipse occurs when the new Moon passes between the Sun and the Earth, casting a shadow on the Earth. There are three types of solar eclipses: annular, partial, and total.

A partial solar eclipse occurs when the Sun and the Moon are not quite lined up. In this case, the Moon covers only a section of the Sun. This kind of eclipse usually goes unnoticed by most people on Earth because the sunlight is scarcely dimmed.

A total solar eclipse, however, is much more spectacular. At totality, the disc of the Sun is completely obscured by the new Moon, and only the ghostly solar corona and perhaps gigantic solar flares are visible around the edges of the Moon. Those parts of the Earth experiencing totality become very dark and it is possible to see stars in the sky.

An annular solar eclipse is similar to a total eclipse except that the new Moon is near apogee and its disc appears slightly smaller than that of the Sun. Thus, a bright ring or annulus of the solar disc remains at maximum eclipse, and the sky does not become dark.

There are at least two and sometimes as many as five solar eclipses every year. Why don't we have a solar eclipse during every new Moon? This is because the Moon's orbit around the Earth is at an angle to the ecliptic. The new Moon usually passes above or below the Sun as seen from the Earth and thus there is no eclipse. The proper alignment for a solar eclipse occurs only a few times a year.

Another kind of eclipse is a lunar eclipse which occurs when the Moon passes through the shadow cast by the Earth. A lunar eclipse only occurs when the Moon is full and for the same reasons given above, happens only two or three times a year.

A lunar eclipse may be total, partial or penumbral. A total lunar eclipse causes the full Moon to slowly darken as it enters the umbra of the Earth and at totality, the Moon may take on a dark coppery colour. During a partial lunar eclipse, the Moon does not fully enter the umbra of the Earth. A penumbral lunar eclipse is likely to go unnoticed as the Moon passes through the Earth's penumbra and does not dim a great deal.

WARNING! Never look at the Sun with the naked eye!

Use proper solar filters or better yet, project the image of the Sun onto a white piece of paper. However, it is completely safe to view a lunar eclipse with the naked eye.

Eclipses in the Year 2008

Annular Solar Eclipse : 7 February
WARNING! Never look at the Sun with the naked eye!
The annular eclipse will be visible from the peninsula region of Antarctica. The rest of Antarctica, along with New Zealand and the southeast corner of Australia will be able to see a partial eclipse.
01:38 UT	The partial eclipse begins.
03:20 UT	The annular eclipse begins.
03:44 UT	New Moon.
03:55 UT	Greatest eclipse: magnitude = 0.965.
04:31 UT	The annular eclipse ends.
06:12 UT	The partial eclipse ends.
Total Lunar Eclipse : 21 February
The entire eclipse will be visible from South America, eastern half of Central and North America, Greenland, Iceland, northwestern Africa and western Europe. The eclipse will already be in progress for the eastern Pacific region and western parts of Central and North America. Those parts of Africa and Europe not able to view the entire eclipse will see the eclipsed Moon set, along with the Middle East and Asia as far west as India. The eclipse is not visible from Australia, New Zealand or the Far East.
00:35 UT	The penumbral eclipse begins.
01:43 UT	The partial eclipse begins.
03:01 UT	The total eclipse begins.
03:26 UT	Greatest eclipse: umbral magnitude = 1.11
03:29 UT	Full Moon.
03:52 UT	The total eclipse ends.
05:09 UT	The partial eclipse ends.
06:17 UT	The penumbral eclipse ends.
Partial Solar Eclipse : 1 August
WARNING! Never look at the Sun with the naked eye!
This eclipse will be visible from the far northeastern parts of Canada, Greenland, Iceland, most of Europe (except southern France, Greece, part of Italy, Portugal and Spain), most of the Middle East and nearly all of Asia. The path of totality runs from the Canadian province of Nunavut, the northernmost parts of Greenland, Siberia, Mongolia and China.
08:04 UT	The partial eclipse begins.
09:21 UT	The total eclipse begins.
10:12 UT	New Moon.
10:21 UT	Greatest eclipse: magnitude = 1.04.
11:21 UT	The total eclipse ends.
12:38 UT	The partial eclipse ends.
Partial Lunar Eclipse : 16 August
The entire eclipse will be visible from most of Africa, the Middle East, eastern Europe and western Asia as far as India. The Moon will already be eclipsed when it rises for observers in South America and western Europe. Those parts of Asia east of India, along with Australia and New Zealand, will see the beginning but not the end of the eclipse. The eclipse if not visible from most of North America.
18:25 UT	The penumbral eclipse begins.
19:36 UT	The partial eclipse begins.
21:10 UT	Greatest eclipse: umbral magnitude = 0.808.
21:17 UT	Full Moon.
22:44 UT	The partial eclipse ends.
23:55 UT	The penumbral eclipse ends.
