The Sudbury Neutrino Observatory (SNO) is a 1 kiloton heavy water, 10,000 phototube, real-time, state of the art second generation water Cerenkov detector designed primarily to study solar neutrinos. The SNO detector has been taking high quality production neutrino data for the last seven months. Water assays and many electronic and source calibration runs have been performed to study the detector cleanliness, response and systematics. It has met or exceeded all design goals and expectations. ©2000 American Institute of Physics.
