Scientific paper

Photometric observations carried out from October to November 1991 of the symbiotic system EG Andromedae are here presented. The secondary minimum has been repeated with a period of about 480 days, as inferred from the orbital elements (P = 482 days, Skopal et al., 1991). The light curve shape led us to suggest a model in which two hot spots result through evaporation from a low mass red giant by a compact object.
