Description
We present simultaneous spectroscopic observations taken during four observing runs (1996 to 1999) of H_alpha, H_beta, H_epsilon, Ca II H & K, and Ca II IRT lines of the chromospherically active binary BF Lyn. Both components have strong emission in the H_epsilon, Ca II H & K and Ca II IRT lines and a strong filling-in of the H_alpha and H_beta lines have been observed after the application of the spectral subtraction technique. We have found that the hot component (K2 V) is always the most active of the system. The different activity indicators of the hot and cool components show anticorrelated variations with the orbital phase.
