The results are presented of a photoelectric and spectrographic study of the galactic cluster IC 2602. In the investigation, observations of 29 probable and 40 possible members yield a distance of 155 parsecs and cluster age of 10 7 years. It is a poorly-populated cluster and its luminosity function shows a deficiency in the number of stars of spectral type F compared with that predicted by the Initial Luminosity Function. It is suggested that the star-group is a local condensation of the Scorpio-Centaurus association.
