Explanation:
Tomorrow, May 20,
the Moon's shadow will race across planet Earth.
Observers within the 240-300 kilometer wide
shadow track will be able to witness
an annular solar
eclipse as the Moon's apparent size is presently too small to
completely cover the Sun.
Heading east over a period of 3.5 hours,
the shadow path will begin in southern China,
cross the northern Pacific, and reach well into North America, crossing
the US west coast in southern Oregon and northern California.
Along
the route, Tokyo residents will be just 10 kilometers
north of the path's center line.
Of course a
partial
eclipse will be visible from a much larger area
within North America, the Pacific, and eastern Asia.
This safely filtered telescopic picture was taken
during the annular eclipse of January 15, 2010 from
the city of Kanyakumari at
the
southern tip of India.
