PHOTOMETRY OF AMOR ASTEROIDS 1036-GANYMEDE AND 1627-IVAR

The photometric observations of Amor asteroids 1036 Ganymede (BV bands ) and 1627 Ivar (V band) were carried out on 10 nights in 1989 May-Jul y and on 19 nights in 1990 May-August, respectively. The obtained comp osite light curve of Ganymede is markedly asymmetric with an amplitude 0.13 mag. By contrast, Ivar light curves are rather symmetric and sho w very large amplitude with considerable changes (from 1.05 to 1.4 mag ). Magnitude-phase dependences obtained at phase angle ranges of a app roximate to 10 degrees-30 degrees for Ganymede and alpha approximate t o 18 degrees-54 degrees for Ivar are represented by the coefficients 0 .020+/-0.002 and 0.024+/-0.002 mag deg(-1), respectively.
