Sept 2004 9 - 09:30 UT: M1.5 flare, halo CME An M1.5 Flare Triggered by a Multireconnection Process P. Romano · F. Zuccarello · L. Contarino Solar Phys (2007) 240: 49–61 The analysis of full-disk SOHO/MDI magnetograms and of WL and 171 Å TRACE images shows in fact that both flux emergence and horizontal displacements of photospheric flux concentrations have a key role in triggering the event.
