The family, one of the oldest in the asteroid belt, is composed of mostly by S-complex asteroids, and have been associated with ordinary chondrites. Nonetheless, the same region also shows an overdensity of C-complex asteroid which highly exceed the expected contamination by interlopers. We propose to use the NASA IRTF Spex instrument to investigate the 0.7-2.3 microns spectra of members of the family to access the level of composition diversity of family, and constrain the mechanisms of its formation and evolution.
