Scientific paper

Simultaneous optical and IUE observations of a flare on UV Ceti in 1980 are reported. The IUE spectra show only slight increase of C IV line emission. The optical spectrophotometric observations show, from Balmer line profiles, turbulent broadening in quiescent and flare spectra, and downward-directed flow (of 100 km/sec) during the flare. The latter is particularly reminiscent of solar flares, and probably arises from the formation of a chromospheric condensation, as modeled for solar flares.
