Abstract:
We present all available UBV photometry of the symbiotic binary EG And
obtained during the last 10 years. The light curves display a double
wave through one orbital cycle. It is shown that this behaviour cannot
be explained by eclipses of the two detached sources of the continuum
radiation. The present models of EG And are not able to simulate
satisfactorily variation in both the far ultraviolet and the optical
continuum.
