  We report on the detection in Sloan Digital Sky Survey data of a 45 degree
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 1.4 degrees. 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.
