Resumen:
We report the serendipitous young Large Magellanic Cloud cluster, NGC 1971,exhibits an extended main-sequence turnoff (eMSTO) possibly originated by mostly a realage spread. We used CT1 Washington photometry to produce acolour-magnitude diagram (CMD) with the fiducial cluster features. From its eMSTO,we estimated an age spread of ~ 170 Myr (observed age range 100-280 Myr), once observational errors,stellar binarity, overall metalicity variations and stellar rotation effects weresubtracted in quadrature from the observed age width.
