Simultaneous Optical and EUVE Observations of a Flare on AD Leo

An 80,000 second pointed observation of the flare star AD Leo was carried out during 1-3 March 1993 (UT) by EUVE. Concurrent optical monitoring observations were made using three telescopes at Lick Observatory and two telescopes at McDonald Observatory. On 2 March 1993 (UT), the first simultaneous optical and EUV observations of a stellar flare were obtained. The optical data include multi-color photometry, and low and high resolution spectroscopy. We present the data for this flare and compare it to previously observed stellar flares.
