High speed photoelectric photometry in the U-filter revealed twenty-four stellar flares on G9 - 38 AB in 4.5 h. An average of five flares per hour makes this star one of the most frequently flaring stars in the solar neighborhood. Eleven percent of the U-filter flux received from the system is due to flare generated photons. This is a small value compared to other flare active systems of similar luminosity, such as UV Cet and V780 Tau. The average flare decay time is close to that of V780 Tau, but twice as large as that of UV Cet.
