The
shadow of moon’s antumbtal begins in the north pacific ocean and the eastern
Asia where it ending of the western united states. This shadow produces a
partial eclipse. That is visible to the much larger region. East Asia, Green
land, North America, North pacifi are the covering areas of this moon’s
penumbrals shadow.
This
announcement for the travellers of the USA
that going for the eclipse. You have to remember this in your minds. May
20th afternoon is the eclipse occure in time.
Description of
the 2012 Annular Solar Eclipse
The 2012 May 20 eclipse occurs at the Moon's descending
node in central Taurus. An annular eclipse will be visible from a 240 to 300
kilometre-wide track that traverses eastern Asia, the northern Pacific Ocean
and the western United States. A partial eclipse is seen within the much
broader path of the Moon's penumbral shadow, that includes much of Asia, the
Pacific and the western 2/3 of North America.
The annular path begins in southern China at 22:06 UT.
Because the Moon passed through apogee one day earlier (May 19 at 16:14 UT),
its large distance from Earth produces a wide path of annularity. Traveling
eastward, the shadow quickly sweeps along the southern coast of Japan as the
central line duration of annularity grows from 4.4 to 5.0 minutes.
Tokyo lies 10 kilometres north of the central line. For
the over 10 million residents within the metropolitan area, the annular phase
will last 5 minutes beginning at 22:32 UT (on May 21 local time). The annular
ring is quite thick because the Moon's apparent diameter is only 94% that of
the Sun. Traveling with a velocity of 1.1 kilometres/second, the antumbral
shadow leaves Japan and heads northeast across the Northern Pacific. The
instant of greatest eclipse occurs at 23:52:47 UT when the eclipse magnitude [2] reaches 0.9439. At that instant, the duration of
annularity is 5 minutes 46 seconds, the path width is 237 kilometres and the
Sun is 61° above the flat horizon formed by the open ocean.

The shadow passes just south of Alaska's Aleutian Islands
as the central track slowly curves to the southeast. After a 7000
kilometre-long ocean voyage lasting nearly 2 hours, the antumbra finally
reaches land again along the rugged coastlines of southern Oregon and northern
California at 01:23 UT (May 20 local time).
Redding, CA lies 30 kilometres south of the central line.
Nevertheless, it still experiences an annular phase lasting 4 1/2 minutes
beginning at 01:26 UT. It is already late afternoon along this section of the
eclipse path. The Sun's altitude is 20° during the annular phase and decreasing
as the track heads southeast. Central Nevada, southern Utah, and northern
Arizona are all within the annular path.

By the time the antumbra reaches Albuquerque, NM (01:34
UT), the central duration is still 4 1/2 minutes, but the Sun's altitude has
dropped to 5°. As its leading edge reaches the Texas Panhandle, the shadow is
now an elongated ellipse extending all the way to Nevada. Seconds later, the
antumbra begins its rise back into space above western Texas as the track and
the annular eclipse end.
During the course of its 3.5-hour trajectory, the
antumbra's track is approximately 13,600 kilometres long and covers 0.74% of Earth's
surface area. Path coordinates and central line circumstances.
Partial phases of the eclipse are visible primarily from
the USA, Canada, the Pacific and East Asia. Local circumstances for a number of
cities are found in (Canada, Mexico and Asia) and (USA). All times are given in
Universal Time. The Sun's altitude and azimuth, the eclipse magnitude and
obscuration are all given at the instant of maximum eclipse.
