Abstract
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.
Highlights
Solar atmosphere is mainly composed of three layers: the photosphere, the chromosphere and the corona
Our white light observations during total phase showing that the relatively indicate the largest recorded extension of white light corona as shown in Figure 1, we can notice that the existence of different zones in white light corona observations
Prominence activity appears on solar limb through inner part of solar corona during total phase of solar eclipse
Summary
Solar atmosphere is mainly composed of three layers: the photosphere, the chromosphere and the corona. [1] used images with high spatial resolution to show the dark cavities surrounding prominences. [4] used high-resolution movies in 193 Å from Atmospheric Imaging Assembly (AIA) on Solar Dynamic Observatory to show apparent rotation of a prominence observed during a coordinated. They found that the Doppler pattern observed in H-Alpha couldn’t be interpreted as rotation of the cool plasma inside tornado. [5] described the white light coronal structure during six total solar eclipses. We will show the stratified structure of inner and outer part of white light corona during total solar eclipse 2006 by using our observations from Salloum, Egypt. We will describe the coronal structure from different locations along the track of total solar eclipse, and we will compare the magnetic field structure our processed and published images
