Lightcurves and phase function of asteroid 44 Nysa during its 1979 apparition

Abstract Lightcurves of asteroid 44 Nysa obtained during 20 nights in 1979 as part of a global campaign are presented. The synodic period was 6 h 25 m .3. The phase coefficient of the primary maximum was 0.026 mag/deg and the absolute V magnitude 7.05. The phase function is linear from 2° to 25°; no opposition effect is present.
