Tidskriftsartikel (refereegranskat)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 presented. The spin vector direction was determin
