IUE/OPTICAL/VLA flares on AD Leo

Dale E. Gary; P. B. Byrne; C. J. Butler

We discuss joint observations of flares on the dMe star AD Leo made with IUE, the VLA, and the Tinsley photometer at the University of Hawaiis 24-inch reflector on Mauna Kea. We find that optical emission is correlated with C IV while radio emission is better correlated with He II. We reach some tentative conclusions concerning timescales and source characteristics.
