August 1: Total Solar Eclipse



It is eclipsing in the other part of the globe right now. I was envious when I knew about this because the Philippines won't experience the total solar eclipse for this year.

According to National Geographic : The sun will be completely obscured for just under two and a half minutes, "a tad on the short side," according to astrophysicist Fred Espenak, an eclipse expert based at the NASA Goddard Space Flight Center.

A typical eclipse lasts for three minutes, Espenak said, and the longest possible is seven and a half minutes.

When it starts, this year's full eclipse will be visible from a narrow arc spanning the Northern Hemisphere.

Its path will begin in Canada and continue northeast across Greenland and the Arctic, then southeast through central Russia, Mongolia, and China.

The eclipse will start around 8:30 a.m. Greenwich mean time in the eastern part of the arc, leading to totality in just under an hour.

In a much wider swath of the globe—including northeastern North America along with most of Europe and Asia—people will be able to see a partial eclipse.

TRIVIA: About 25 percent of eclipses are total eclipses, and there are about seven of these a decade, Espenak said. But at any given geographic location, a total eclipse will be visible an average of once in 375 years.
