Resumo

Solar magnetic loop structures can exist in a broad range of spatio-temporal scales and their mutual interactions are described by nonlinear processes of magnetic reconnection triggered as a secondary regime by a primary MHD instability. From the application of wavelet analysis on decimetric time series as a counterpart of spatio-temporal flare loop observations we derive, using Tajima's model for quasi-periodic MHD coalescence, possible ranges of minimum Sagdeev potential. From this parameter we obtain the Alfven period of nonlinear oscillation for a typical mutual solar loop interaction observed by SOHO and TRACE. (AU)
