We report a measurement of the time-dependent ratio of D-0 -> K+ pi(-) to D-0 -> K- pi(+) decay rates in D*+-tagged events using 1:0 fb(-1) of integrated luminosity recorded by the LHCb experiment. We measure the mixing parameters x(/2) = (-0:9 +/- 1:3) x10-(4), y(/) = (7:2 +/- 2:4) x 10(-3), and the ratio of doubly- Cabibbo- suppressed to Cabibbo-favored decay rates R-D = (3.52 +/- 0:15) x 10(-3), where the uncertainties include statistical and systematic sources. The result excludes the no-mixing hypothesis with a probability corresponding to 9.1 standard deviations and represents the first observation of D-0 - (D)over bar(0) oscillations from a single measurement.
