Abstract • We report on the detection in Sloan Digital Sky Survey data of a 45° tidal stream of stars, extending from Bootes to Ursa Major, which we associate with the halo globular cluster NGC 5466. Using an optimal contrast, matched-filter technique, we find a long, almost linear stellar stream with an average width of 1.4d. The stream is an order of magnitude more tenuous than the stream associated with Palomar 5. The stream's orientation on the sky is consistent to a greater or lesser extent with existing proper-motion measurements for the cluster.
