Free Proton Charged Current Cross Section using MiniBooNE Anti-Neutrino Data

The MiniBooNE experiment completed neutrino running in the fall of 2005 and switched to anti-neutrino running in early January in 2006. The anti-neutrino data sample provides a set of charged current quasi-elastic events which may be used to extract a measurement of the free proton cross section. This talk will focus on the status of the $\overline{\nu_{\mu}}$ CCQE free proton cross section measurement.
