MiniBooNE has performed a search for numu to nue oscillations with

sensitivity to Dm^2 near 1eV^2, with the goal of confirming or ruling

out the LSND numubar to nuebar oscillation signal. MiniBooNE uses a

high intensity neutrino beam at Fermilab whose average muon neutrino

energy is ~800 MeV. During its neutrino data run, MiniBooNE

accumulated 5.6E20 protons on target and more than one million

neutrino interactions in the detector. MiniBooNE performed a "blind"

analysis, where all analysis selections and fitting procedures were

determined before candidate electron neutrino events were examined.

First oscillation results will be presented.
