We report the detection of a long-duration optical flare in the recenltly discovered, X-ray selected, chromospherically binary 2RE J0743+224. The high resolution echelle spectroscopic observations taken in 12-21th January 1998 exhibit a dramatic increase in the chromospheric emissions (H_alpha and CaII IRT lines) that we interpret as a flare based on: the temporal evolution of the event, the broad component observed in the H_alpha line profile, the detection of the HeI D_3 in emission and a… Expand
