The event was observed by the Solar Dynamics Observatory and Solar Terrestrial Relations Observatory. The erupting filament height is fitted with the sum of a linear and exponential function. These two phases evidence the tether-cutting reconnection as well as magnetic instability. Close to the erupting filament, a stable filament remains in the core of the AR. The EUV loops, located above the nearly joining ends of the two filaments, first contract in phase, then expand and reach a new stable configuration. These observations cannot be explained by the models that interpreted contraction within a bipolar magnetic configuration. New simulations are required to broaden the complexity of the configurations studied. |
