Velocities of Flare Kernels and the Mapping Norm of Field Line Connectivity
Original language description
We report on observations of flare ribbon kernels during the 2012 August 31 filament eruption. In the 1600 and 304 angstrom channels of the Atmospheric Imaging Assembly, flare kernels were observed to move along flare ribbons at velocities v(parallel to) of up to 450 km s(-1). Kernel velocities were found to be roughly anticorrelated with strength of the magnetic field. An apparent slipping motion of the flare loops was observed in the 131 angstrom only for the slowest kernels moving through the strong-B region. In order to interpret the observed relation between B-LOS and v(parallel to), we examined the distribution of the norm N, a quantity closely related to the slippage velocity.
