Resumen:
We analyze the observations of two flares from NOAA AR
10501 on 20 November, 2003. The flares are homologous, exhibit four
ribbons and are located in a quadrupolar magnetic configuration. The evolution
of the ribbons suggests that the first eruption is triggered by ?tether
cutting? (with subsequent quadrupolar reconnection as in the ?magnetic
breakout? model), whereas the second one is consistent with the ?magnetic
breakout? model. Another interesting feature of our observations is the interaction
of two filaments elongated in the north-south direction. The filaments
merge at their central parts and afterwards change their orientation to
the east-west direction. This merging and splitting is closely related to the
evolution found in an MHD simulation as a result of reconnection between
two flux ropes.
