Light curves of asteroid 51 NEMAUSA during its 1989 apparition Light curves of 51 Nemausa were obtained during 5 nights in 1989. It isfound that the shape of the light curves of the asteroid is stronglydependent on the phase angle. The maximum amplitude increases from 0.11to 13 m as the phase angle increases from 5.4 to 26.5 deg. The meanvalue of the phase coefficient is 0.045 magnitude/deg.
