Abstract
We present CCD data in the Johnson passbands B and V of the young asso ciation NGC 1962-65-66-70 in the Large Magellanic Cloud. We find the a ssociation to show an age spread in the range 4 to 9 Myr. Some signs f or a propagation of star formation from the south-eastern to the north ern part of the region can be found, but they are based on very few st ars. The slope of the luminosity function is gamma = 0.27 +/- 0.02 for stars of the magnitude range -8 < M(V) < +2 mag. The slope of the ini tial mass function is x = 1.2 +/- 0.1 in the mass range 2.5 < M < 20M. which is compatible with the value for the solar vicinity (x = 1.35). We discuss some of the bright stars, in particular the star HDE 269 5 51, which turns out to be a multiple system.
