Magnetic topology analysis of an M6.7 solar flare
Abstract
We study an M6.7 solar flare that occurred on October 27, 2003 (12:27 UT). We use data in different wavelenghts: magnetograms from the Michelson Doppler Imager (SoHO/MDI), images from the Halpha Solar Telescope for Argentina (HASTA) and Extreme Ultraviolet Imaging Telescope (SoHO/EIT).We analyze the magnetic field evolution and compute the coronal field to identify the energy release site. From this study, we find evidence of a magnetic null point in the corona. We relate the chromospheric and EUV brightenings to the magnetic field topology in its neighborhood. FULL TEXT IN SPANISH
