 Other observations include a period of hours with an amplitude of magnitude by Richard Binzel from June 1984 (), and a period of hours with an amplitude of magnitude by the Spanish group of asteroid observers, OBAS, in November 2015 ().In 2018, Czech astronomers Josef Ďurech and Josef Hanuš published a modeled lightcurve using photometric data from the "Gaia" spacecraft's second data release.It showed a sidereal period of hours (), and gave two spin axes at (18.0°, 4.0°) and (192.0°, 32.0°) in ecliptic coordinates (λ, β).
