Abstract
Abstract Evidence is presented for the presence of a transient emission feature at 1524 Å in the far ultraviolet spectrum of 21 Com recorded by the International Ultraviolet Explorer during the 1979 event. This event is characterized by he sudden appearance of broad and intense absorption features shortwards of 1720 Å. The emission feature at 1524 Å is tentatively identified as a Si i line also present in the FUV spectra of quiescent dMe dwarfs. During the event, the flux level in the continuum adjacent to this line is about 1.6 times higher than in the mean spectrum outside event.
