13-cm radar observations of this asteroid from the Arecibo Observatory between 1980 and 1985 were used to produce a diameter estimate of 108 km.[6]
In 1990, the asteroid was observed for four nights from the Collurania-Teramo Observatory in Italy, producing an asymmetric light curve that showed a rotation period of 10.927 ± 0.001 hours and a brightness variation of 0.17 ± 0.02 in magnitude. This period confirms a value independently determined in 1971
