The DONUT collaboration has observed four events in a hybrid emulsion spectrometer consistent with tau neutrino charged-current interactions. The resulting tau lepton is identified by its decay into a single charged particle. The expected background of charm decays and secondary interactions is .34 +/- >.05 events. The probability that all tau neutrino candidates are due to background proceesses is 1.1 x 10-4.
