Abstract
Lightcurves in the uvby Strömgren filters have been obtained for the asteroids 12 Victoria, 30 Urania, 93 Minerva, 230 Athamantis and 192 Nausikaa during their oppositions in 2000. Synodic periods of 8.66, 13.69, 24.04 and 13.62 hours and y filter amplitudes of 0.^{m}2, 0.^{m}3, 0.^{m}14 and 0.^{m}2, have been found for 12 Victoria, 30 Urania, 230 Athamantis and 192 Nausikaa, respectively. Lightcurve amplitude smaller than 0.^{m}03 in the y filter has been found for 93 Minerva. Lightcurves in the BVI filters have been obtained for the asteroid 7357 1995 UJ7 during its opposition this year. A synodic period of 2.856 hours and an amplitude of 0.^{m}18 in the V filter have been derived.
