Abstract
BVR photometric series of observations of potentially hazardous asteroid (415029) 2011 UL21 were obtained at the Astronomical Station of Vidojevica around its close approach to the Earth on 2018 July 1. From these observations, the color indices V − R = 0.48 ± 0.07 and B − V = 0.89 ± 0.06 were determined, suggesting R- or S-type taxonomic classification of the object. The observed small lightcurve amplitude suggests a nearly spherical shape of the asteroid.
