Abstract
We report the discovery of tidal tails around the high-latitude Galactic globular cluster NGC 5466 in Sloan Digital Sky Survey (SDSS) data. Neural networks are used to reconstruct the probability distribution of cluster stars in u,g,r,i and z space. The tails are clearly visible, once extra-galactic contaminants and field stars have been eliminated. They extend roughly 4 degrees on the sky, corresponding to about 1 kpc in projected length. The orientation of the tails is in good agreement with the cluster's Galactic orbit, as judged from the proper motion data.Comment: 4 pages, 4 figures, submitted to The Astrophysical Journal (LettersKeywords
