Relationship between filament disappearance events and interplanetary disturbances studied by a 3-D kinematic method

Using a 3-D kinematic method, the connection between solar filament disappearance events (FD) and interplanetary disturbances is investigated. Nineteen events of interplanetary disturbances observed at 1AU were chosen as studying samples. All FD events which occurred 2-5 days earlier then the investigated samples were considered as probable disturbance sources. Sources surface field (at 2.5 Rs) calculated from the photospheric magnetic field observations using a potential field model, was taken as the background magnetic field. We simulated the propagation and interaction of the interplanetary disturbances caused by the selected FD events and the results are compared with simulations and observations. Good connections could be found between FD events and interplanetary disturbances for 63% of the total events. Our results indicate FD events are important candidates as the source of interplanetary disturbance events.
