Abstract: Results are presented for a large flare detected simultaneously on the RS CVn star, II Peg, by the X-ray satellite Ginga and from ground-based Johnson U-band measurements. The total U-band flare energy is determined. Using a smooth-burst model, the combined U-band plus X-ray radiative output is estimated.
