MUSICOS 1998: Observations of Rotational Modulation and Flares on the RS CVn Binary HR1099
We present simultaneous and continuous observations of Hα, Hβ, ion{Na}{1} D1, D2, ion{He}{1} D3 and ion{Ca}{2} H & K lines of the chromospherically active binary HR 1099. We have observed HR 1099 for more than 3 weeks almost continuously and monitored two flares. An increase in Hα and ion{Ca}{2} H & K, Hβ and ion{He}{1} D3 and a strong filling-in
