Scientific paper

The young LMC cluster NGC 2214 has been suspected to be in the stage of merging two clusters, because it shows a significantly elliptical core structure embedded in an almost spherical halo and two central sub-components. Recently Sagar et al. (1991) have claimed that NGC 2214 has two distinct supergiant branches with ages of about 60 Myr and about 170 Myr, respectively. Based on deep UBVI CCD photometry, we suggest that NGC 2214 shows only one supergiant branch of age about 60 Myr. This result implies either that NGC 2214 is a single cluster or, if it is a binary cluster, it may consist of two components of similar age.
