[6] A photoelectric study was performed of this minor planet in 1991 at the Konkoly Observatory in Hungary.
The resulting light curve showed a synodic rotation period of 6.94 ± 0.29 hours with a brightness variation of 0.2 in magnitude.
It was estimated to have an absolute magnitude of 8.459 ± 0.013 with a diameter of 96–118 km (60–73 mi) and an albedo of 0.06–0.04.
[8] Infrared observations made in 1982 at Konkoly showed a rapid variation that seemed to suggest a shorter rotation period of 1.5 hours; one of the fastest known at the time.
[6] A larger diameter value of 123.41 ± 4.07 km was obtained from the Midcourse Space Experiment observations, with an albedo of 0.0557 ± 0.0039.
