At 21:57 UT, on Thursday, July 8, 2010, this 50 km wide asteroid occulted the star Delta Ophiuchi in an event lasting about five seconds. The occultation path crossed central Europe along a band that ran through Stockholm, Copenhagen, Bremen, Nantes and Bilbao.
This is a member of the dynamic Maria family of asteroids that were probably formed as the result of a collisional breakup of a parent body.[5]
