Abstract
By means of VI CCD photometry we identify a new globular cluster in
the Galaxy: ESO 280-SC06. The images and Colour Magnitude Diagrams
indicate that we are dealing with a sparsely populated globular
cluster, showing a compact core. The cluster is located in Ara,
projected at only 12.6o from the plane, and appears to be
metal poor (![[FORMULA]](img1.gif)
). We derive a reddening
E(B-V) = 0.07 and a distance from the Sun
![[FORMULA]](img2.gif)
= 21.9 kpc. It is a halo globular
cluster on the opposite side of the Galaxy.
