  The results from the initial exposure of the MINOS detectors to neutrinos
produced by the Fermilab NuMI beam are reported here. The exposure consisted of
1.27 x 10^{20} 120 GeV protons incident on the NuMI target. The data show the
observation of 215 neutrinos with energies below 30 GeV while 336 +/- 14.4
events were expected. The data are consistent with nu_mu disappearance via
neutrino oscillations.
