We present the results of photometric observations of the Apollo asteroid 1991 VH. Its lightcurve consists of two components: the first is the rotational lightcurve with periodPs= (0.109327 ± 0.000003) d and amplitude 0.09 mag, while the second, with period Pl= (1.362 ± 0.001) d, shows two minima with depth 0.160.19 mag, each with a duration of about 0.10 d, and little or no variation at phases between them.
