Abstract
Photometric observations of 1999 HF1 reveal that its lightcurve has two components of low amplitudes (0.10–0.12 mag) and different periods (2.3191 and 14.02 h). It is likely another binary near-Earth asteroid; its lower limit on the secondary-to-primary-diameter ratio is ≈0.2, the radius of the mutual orbit is (2.0±0.3)× the effective primary diameter, the primaryʹs bulk density is >2.0 g/cm3, and it belongs to the E/M/P taxonomic class.
