Descripción
U,B,V,R,I and simultaneous near infrared J,H,K light curves of the RS
CVn system ER Vul are presented. A study of the mean levels compared to
other years indicates that the system is highly variable, giving
evidence that important changes occur over one month. Colours show an
ultraviolet and infrared excess. There seems to be a contribution from a
hot plasma in the observed fluxes, with temperatures between
104 - 5×104K.
