It was discovered by Auguste Charlois on 23 November 1892, in Nice.
Observations of an occultation of a bright 5.5 magnitude star on 17 September 2002, produced seventy-five chords indicating an ellipsoid of 111×90 km.[3]
Observations of an occultation on 15 November 2005, near Grass Valley, California, produced five chords indicating an incomplete outline of 126×111 km.[2] This larger result may be caused by a different orientation of the asteroid as it passed in front of the star.[citation needed]
