Lightcurve An ambiguous
lightcurve was obtained through photometric observations by Czech astronomer
Petr Pravec in 1998. The light-curve gave a
rotation period of hours with a brightness amplitude of 0.20 in
magnitude. The alternative period solution is hours with an amplitude of 0.22 in magnitude ().
Diameter and albedo The
Collaborative Asteroid Lightcurve Link (CALL) assumes a standard
albedo for stony asteroids of 0.20 and calculates a diameter of 540 meters, based on an absolute magnitude of 18.7. Observations with the
Spitzer Space Telescope using its
Infrared Array Camera at wavelengths between 3.6 and 8.0 micrometers, gave an average diameter of 399 meters with a higher albedo of 0.37. == Notes ==
