Penumbral lunar eclipse visible in Vietnam

QĐND – Saturday, December 18, 2010, 22:18 (GMT+7)

It will happen in Vietnam on December 21 from 5.30pm to 6pm before the total lunar eclipse ends.

On the same day, North America and part of South America, Central Europe, and East Africa can watch the total lunar eclipse while East Asia will only witness partial eclipse.

A penumbral eclipse occurs when the Moon passes through the Earth’s penumbra. The penumbra causes a subtle darkening of the Moon’s surface. A special type of penumbral eclipse is a total penumbral eclipse, during which the Moon lies exclusively within the Earth’s penumbra. Total penumbral eclipses are rare, and when these occur, that portion of the Moon which is closest to the umbra can appear somewhat darker than the rest of the Moon.

It is difficult to watch an eclipse in Vietnam because it occurs when the Moon begins rising.

Dang Vu Tuan Son, Chairman of the Vietnam Amateur Astronomy Club, said penumbral lunar eclipse can be observed by eyes but it will be more beautiful when watched through binoculars, astronomical telescopes or cameras. It occurs within a short time and is difficult to watch in the inner city because of the city lights.

Eclipse plunges central, east Africa into semi-darkness

In World on January 15, 2010 at 9:18 am

An annular eclipse raced across central and eastern Africa Friday, briefly reducing the Sun to a blazing ring surrounding a sombre disk.

The moon begins to obstruct the view of the sun from earth in Colombo on January 15, 2010. The longest lasting solar eclipse of the last millenium was first visible in Sri Lanka’s north and northeastern areas.

The solar coverup, visible in a roughly 300-kilometre (185-mile) band running 12,900 kms (8,062 miles), will at one point set a duration record that will remain unbeaten for more than a thousand years.

In the Ugandan capital Kampala motorcycle taxi drivers stopped on street corners to share dark glasses and gaze up at the sky.

Some residents were afraid of the intensity of the light.

“Can’t it burn someone? You can’t even look direct because I’m fearing for my eyes. I’m fearing it can burn me,” said Angela Namukwaya, a shopkeeper in a Kampala suburb.

In Kenya, John Saitega, a 34-year-old Maasai and father of six in Olte Tefi 50 kilometres (30 miles) south of Nairobi, said he and his friends learned of the eclipse and the risk gazing at it carries for their eyesight from local radio and television.

They were all sharing one pair of dark goggles and taking turns to look at the Sun, he said.

“It’s getting interesting. Birds are singing. It’s actually getting cold here. It looks like night now,” he told AFP.

An annular eclipse occurs when the Moon passes directly in front of the Sun but does not completely obscure it, thus leaving a ring — an annulus — of sunlight flaring around the lunar disk.

The Moon’s shadow first struck the southwestern tip of Chad and western Central African Republic at 0514 GMT and then flitted across Uganda, Kenya, and Somalia.

The lunar umbra, or shadow was set to cross the Indian Ocean, Bangladesh, India, Myanmar and China before expiring in the Shandong peninsula at 0859 GMT.
