The Sloan Digital Sky Survey at the millennium

The Sloan Digital Sky Survey (SDSS) is carrying out a digital photometric and spectroscopic survey over pi steradians in the northern Galactic cap, plus a smaller area in the south. An array of CCD detectors is used in drift-scan mode to image the sky in five passbands to a limiting magnitude of r' similar to 23. Selected from the imaging survey, 10(6) galaxies, 10(5) quasars and similar to 105 stars will be observed spectroscopically. To date we have imaged 1700 square degrees and obtained almost 100,000 spectra. I describe the current status of the survey, which is now in regular operation, and present some preliminary results obtained from commissioning data which are of relevance to dark matter.
