Abstract
The Sloan Digital Sky Survey (SDSS) is carrying out a digital photometric and spectroscopic survey over π 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’ ~ 23. Selected from the imaging survey, 106 galaxies, 105 quasars and ~ 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.
