PPT-Global Structure of the Solar Corona

Roberto J Pérez UPRM Charles Kankelborg MSU Sarah Jaeggli MSU Abstract The AIA instrument on the Solar Dynamics Observatory obtains images of the sun in seven different extreme ultraviolet wavebands Each filter produces images with distinctive appearance that is apparent to experienced observers Subjective descriptions abound in the literature and in conference presentations as do qualitative explanations of the physical reasons for these differences We seek a quantitative description of the image properties with the aim of understanding what the general image properties indicate about the temperature structure of the corona Our preliminary results obtained at multiple heliocentric angles above and below the limb show that some channels consistently present a high or low intensity contrast which we attribute to the differing temperature density and filling factor of the structures imaged We also investigate the power spectra characteristic of each waveband .

Because the sun is made of gas, no sharp boundaries exist between its various layers. Keeping this in mind, we can divide the sun into four parts: the solar interior; the visible surface, or photosphere; and two atmospheric layers, the chromosphere and corona.. Chashei. I.V., .
