During
total solar eclipses, we can observe the outer atmospheric layers of the sun
(chromosphere and corona). The solar corona extends to several solar radii
depending on the sunspot cycle. Basic coronal structures such as polar
streamers, helmet type structures were?observed?during the 2006 total
solar eclipse. Our total solar eclipse 2006 observations through?both White light corona and
H-Alpha filter allowed us to describe coronal structures and Prominence
Activity. We found that the solar corona is extended to 4 times of solar radii,
the existence different zones of white light corona were shown, moreover, we
compared the defined features of solar corona at different observing locations
along the track of total solar eclipse 2006. The solar limb activity was
studied during both of partial and total eclipse phases by using H-Alpha and
white light observations from Salloum, Egypt. We got same prominence activity
during partial and total phases of the solar eclipse and recorded three
prominences on solar limb. Finally, our processed image in a good agreement
with the published?processed images?was?observed from different locations along the track of total eclipse,?added, similar magnetic
field structure shown in our processed image and published one.
