Photometry And Models Of Selected Main Belt Asteroids Iii. 283 Emma, 665 Sabine, And 690 Wratislavia

Photometric observations of 283 Emma ( 1998, 2000, 2001, 2004), 665 Sabine ( 1998, 1999, 2001, 2004, 2005), and 690 Wratislavia ( 1998, 2000, 2004, 2005-2006) carried out on 44 nights at two observatories are presented. Using all available lightcurves, the spin vectors, senses of rotation, and shape models for these three asteroids have been determined.
