[16.18] Coronal `Tadpoles' Observed by TRACE

The X1.5 flare event observed by TRACE in 195 Åon 21 April 2002, showed dark, downward-propagating features over the flare arcade which we call `coronal tadpoles.' We analyzed these features and determined their distinguishing characteristics. Estimating plasma densities inside the features, we determined that they are of very low density and possibly >10 million K. We propose that the coronal tadpoles my be interpreted in terms of kink modes of the flaring current sheet filled by hot, rarefied plasma.
