Abstract
We present observations at 5 GHz of flaring and quiescent emission fro m the red dwarf star YZ CMi, obtained with the Jodrell Bank broad-band interferometer. Weak (1 to 2 mJy) quiescent emission varying over tim e-scales of hours was detected, in addition to a strong outburst on 19 88 October 6 which reached 42 mJy and lasted several minutes. Low-leve l flaring at approximately 15 mJy and of short duration (<20 s) also o ccurs continuously at a rate of 5 to 6 events per hour.
