Using the CLEO II data sample, with an integrated luminosity of 1.8 fb−1 at and near the Υ(4S) resonance, we have observed a signal for D0→K+π−, which could be due to either D0D¯0 mixing or doubly Cabibbo suppressed decay, or a combination of the two. We find scrB(D0→K+π−)/scrB(D0→K−π+)=0.0077±0 .00...
