Reported here are results, which have been published in [6], from the MINOS experiment from its first year of data-taking with neutrinos from Fermilab's NuMI beam. During this period, 1.27x10{sup 20} protons were delivered to the neutrino target. MINOS consists of two detectors, located 1 km and 735 km from the neutrino beam origin. A deficit of {nu}{sub {mu}} neutrinos are observed in the far detector, with only 215 events observed below 30 GeV, compared to 336{+-}14 events expected in the absence of neutrino oscillations. The data are consistent with neutrino oscillations with |{delta}m{sub 23}{sup 2}| = 2.74{sub -0.26}{sup +0.44}x10{sup -3} eV{sup 2} and sin{sup 2}(2{theta}{sub 23})>0.87, at the 68% confidence level.
