Abstract:
    We present results of a study that combines UBVI photometry, MK
    spectral classification and proper motions in the area of the, up to
    now unknown, open cluster Ruprecht 58 at the Puppis region.

Description:
    CCD observations in the UBVI system were carried out in the field of
    Ruprecht 58 on the nights of December 24 and 25, 2003, at the Complejo
    Astronomico El Leoncito, CASLEO, Argentina.

Note (1): (::) denotes photometric errors e_phot>0.1.

Note (2): m = probable cluster members according to the photometric
              criterion explained in Sect. 3
Note (3): Note as follows:
    PME = probable member by extension from an extrapolation procedure
          using the parameters derived in Sect. 4.
    NME = non-member by extension from an extrapolation procedure using
          the parameters derived in Sect. 4.
