Abstract:
We have obtained CCD photometry in the Johnson V, Kron-Cousins I and
CT1 Washington systems for NGC 2324, a rich open cluster located
∼35° from the Galactic anticentre direction. We measured V
magnitudes and V-I colours for 2865 stars and T1 magnitudes and
C-T1 colours for 1815 stars in an area of 13.6'x13.6' (pixel=0.4")
