الملخص الإنجليزي

The development of the solar physics is one of the topics that depends almost entirely on the performance of the solar remote sensing means being employed.

Nowadays, high resolution solar imagery and high sensitive spectroplarimetry have paved the way for scientists to deepen their researches for more developed and new solar concepts.

The contemporary solar techniques assist in obtaining and reconstructed useful solar images for the photosphere and chromosphere layers and their associated magnetograms. The present work is focused, in general, on analyzing polarized solar images and in particular reconstructed quiet Sun regions images ( in the visible Fe I λ 6302.5 A˚ and Fe I λ 6301.5 A˚ spectral lines ) and their magnetograms.

These images and magnetograms are usually obtained form worldwide solar research centers.

Recent works are reviewed and the principles of the solar spectropolarimetry are presented. Computer programs for processing solar images and magnetograms have been developed.

The performance of these programs was first tested using filtered solar CCD images obtained from 3.5" (F\17) refracting telescope employed here.

Effects of seeing condition on solar images and ultimately on their magnetograms, evaluating signed and unsigned magnetic fluxes and manifesting strongest magnetic signals in magnetograms and their spatial distribution pattern (useful for locating convective “network” cells) are studied
