We present the results of VRI photometry of the young open cluster IC 2602. Two tex2html_wrap_inline1195 fields were observed in February and May 1991 using the 1-m Swope telescope at Las Campanas. Using theoretical isochrones obtained from D'Antona & Mazzitelli (1994), and allowing for observational and other uncertainties, we identify 78 primary candidate members with 12<V<18.5 from their positions on colour-magnitude diagrams. We compare the cluster field with an offset field of similar galactic latitude and estimate the contamination due to background stars to be large, tex2html_wrap_inline1199, as might be expected given its low galactic latitude. We also compare our photometry with that given for the X-ray detected stars of Randich et al. (1995). We present complimentary narrow band tex2html_wrap_inline1201 photometry for a subset of the stars.
