. Medjante fotometria fotoelectrica BV fueron estudiados 31 EUPHROSYNE, 118 PEITHO en su oposici6n de 1988, y 13 EGERIA, 196 PHILOMENA y 471 PAPAGENA en su oposici6n de 1989, con el fin de determinar su per1odo de rotaci6n, la orientaci6n del polo y la forma de los asteroides. Se presentan las curvas de luz de 118 PEITHO y 13 EGERIA. ABSTRACT. The asteroids 31 EUPHROSYNE and 118 PEITHO at their opposition of 1988, and 13 EGERIA, 196 PHILOMENA and 471 PAPAGENA at their opposition of 1989, have been studied by means of photoelectric photometry BV with the purpose of determining their rotation periods, pole orientation and shapes. The lightcurves of 118 PEITHO and 13 EGERIA are shown. : ASTEROIDS - PHOTOMETRY
