Coronal structure and flattening during total solar eclipse 2006

On the basis of well resolved observations of the solar corona taken at Salloum N-W of Egypt during the total solar eclipse of 2006 “the descending phase of solar cycle 23”, some aspects of the physics of the corona have been studied up to several solar radii. The magnetic structures of the white light corona were studied. The flattening coefficient e characterizes the shape of the isophotes of the whit-light corona and computed as a function of the distance from the disk center. The flattening index e during solar total eclipse 2006 was found to be 0.158. This result is in a good agreement with previous published results.
