One of the most
remarkable coincidences found in nature is the fact that the
Moon and the Sun both appear the same size as seen from Earth.
The Moon, a small, cold, and dark body is only 3,500 km in
diameter while the sun, a self-luminous, gaseous giant, is
1,400,000 km across. The coincidence arises from the fact that
although the sun is 400 times larger than the Moon, it is also
400 times farther from Earth. A direct consequence of this
fortuitous geometry is that during a total solar eclipse, the
Moon occludes the Sun with a nearly perfect
fit.
The fundamental
basis of the solar eclipse is the alignment of the Sun, Moon
and Earth such that some region of Earth passes through the
Moon's shadow. This shadow is composed of two parts: the outer
or penumbral shadow and the inner or umbral shadow. From
within the penumbra, only part of the sun is obscured. In
contrast, the dark, central umbra is the shadow of complete or
total eclipse. During a total eclipse, the umbra sweeps across
Earth from west to east and the course it travels is called
the path of totality. Anyone standing within this zone will
see the Sun completely obscured by the moon for as long as 7
1/2 minutes. At this time, the solar corona is visible as a
halo about the moon and the landscape takes on the appearance
of an eerie twilight. Outside the path of totality but still
within the penumbra, a partial eclipse is seen. The path of
the umbra is rarely more than 300 km wide
THE
EVENT
On Wednesday, 2006
March 29, a total eclipse of the Sun will be visible from
within a narrow corridor which traverses half the Earth. The path of
the Moon's umbral shadow begins in Brazil and extends across
the Atlantic, northern Africa, and central Asia where it ends
at sunset in western Mongolia. A partial eclipse will be seen
within the much broader path of the Moon's penumbral shadow,
which includes the northern two thirds of Africa (Egypt,
Libya), Europe, and central Asia.
If you want to
live this event you need to know that .for a solar eclipse you
have to be in a very specific geographic location So your
select must be Egypt

Solar
Eclipse in Egypt
The high
resolution in Egypt will be in Sallum (The border town
between Egypt & Libya)
The Mediterranean coast at Sallum is the
sunniest climate along the eclipse track save for dusty
locations in the deserts of Libya and Niger. At eclipse time
the dry season is just beginning and Sallum averages about 9.5
sunshine hours per day. about 79 percent of the maximum
possible. Rain is reported on only one day in 10, and the
average cloudiness for the region is under 40 percent. Daytime
temperatures average a comfortable 22°C (72°F) but can reach a
blistering 42°C(108°F). In March migrating low-pressure
systems move either along the coast of North Africa or further
inland, where they are known as Khamsin depressions.
Approaching lows bring southerly winds and sunny weather if
they pass offshore and dusty (but sunny) conditions if they
move inland. Broken high and midlevel cloud and occasional
rainfall follow behind the low. If a strong cold front comes
with the depression, a severe dust storm lasting a few hours
is possible, though such dust storms are much less frequent
than at sites deeper with the Sahara. While these
Mediterranean lows can make eclipse observations a challenge,
only three or four per month are expected on average and
extensive cloud is the exception rather than the rule. The
terrain at Sallum, which is dominated by a 400-meter ridge
just west of the town, will help modify some of the harsher
effects of the passing depressions. The excellent highway
stretching parallel to the Mediterranean coast will facilitate
rapid movement to a new location if cloudy skies
threaten.
