Light curve variations and H-alpha flaring of FK Comae

Multiband photoelectric observations reveal that the rapidly rotating giant FK Com's light curve is rapidly changing with respect to amplitude, shape, and light minimum phase. Analysis of the light curves indicates that these variations are due to rotational modulation by two large, subluminous regi...
