BVIC photometry and classication spec- troscopy is presented for the young open cluster NGC 6604. Additional Echelle spectroscopy of the brightest members is used to check the reddening against the interstellar NaI and KI absorption lines, to measure the cluster radial velocity and to derive the individual rotational velocities. We obtain 1.7 kpc as the cluster distance, an age of 51 0 6 years and a reddening EB V = 1.02 (0:01 from three independent methods). Pre-ZAMS objects are apparently not… Expand
