We have discovered a previously-unknown asteroid family in the inner Main Belt that is located near major dynamical resonances that act as source regions for the NEO population. Because of its location near these sources regions in the inner Main Belt, this newly discovered asteroid family may be a source of NEOs and meteorites such as L chondrites. There is some indication that the asteroid family may have a composition similar to some ordinary chondrite parent bodies. We will investigate some of its members with NIR spectroscopy and compare it with NIR spectra of meteorite samples to test their possible connection with L chondrites. We propose to use two nights in semester 2020B to observe 10 members of this newly-discovered family. We may apply for additional nights in subsequent semesters to confirm the spectra. We think that 10 asteroids is an adequate sample as has been done for similar studies of asteroid family members [McGraw et al. 2018]. PROGRAM_ABSTRACT_END
