Large flare on the red dwarf star UV Ceti

Nature, 1974
ATTEMPTS to measure radio emission occurring simultaneously with the sporadic optical flares on the red dwarf dMe type stars have been hindered by the rarity of large flares. Apart from one case of a flare with an unusually long duration and a peak magnitude of 1.7 (ref. 1) the correlation so far established has been limited to flares of about 1 mag or

Microwave observations of red dwarf flare stars

Advances in Space Research, 1986
Abstract We discuss some recent observations of red dwarf flare stars. When observed over periods of about 8 hours, each of 4 flare star systems displayed at least one major flare at 20 cm. Quiescent emission at 6 cm was seen from UV Ceti and EQ Peg A, but flares were much less frequent at 6 cm than at 20 cm. We also summarize earlier observations of
