Abstract
During the 1991 and 1993 oppositions, photoelectric photometry of the asteroid 675 Ludmilla was carried out. Composite lightcurves in V and colour curve in B - V, as well as magnitude-phase dependences are pres ented. The spin vector direction was determined giving pole coordinate s (lambda(01) = 12 degrees +/- 4 degrees, beta(01) = -45 degrees +/- 6 degrees or lambda(01) = 15 degrees +/- 10 degrees, beta(01) = -35 deg rees +/- 10 degrees and lambda(02) = 205 degrees +/- 10 degrees, pot = -50 degrees +/- 10 degrees), and a retrograde sense of rotation. The sidereal period is P-sid = 0(d).321551.
