Photometry of AMOR Asteroids 1036 Ganymede and 1627 Ivar
Abstract
The photometric observations of Amor asteroids 1036 Ganymede (BV bands) and 1627 Ivar (V band) were carried out on 10 nights in 1989 May-July and on 19 nights in 1990 May-August, respectively. The obtained composite light curve of Ganymede is markedly asymmetric with an amplitude 0.13 mag. By contrast, Ivar light curves are rather symmetric and show very large amplitude with considerable changes (from 1.05 to 1.4 mag). Magnitude-phase dependences obtained at phase angle ranges of α≈10°-30° for Ganymede and α≈18°-54° for Ivar are represented by the coefficients 0.020±0.002 and 0.024±0.002 mag deg-1, respectively.
