摘要：

Colour magnitude diagrams of Terzan 3 and IC 1276 are presented for the first time. The morphology of the horizontal and red giant branches indicates that they are metal rich ([Fe/H] approximate to -0.7). They are considerably reddened, with E(B - V) = 0.72 (Terzan 3) and E(B - V) = 1.16 (IC 1276). Terzan 3 is located at a distance from the Sun d. approximate to 6.5 kpc, and IC 1216 at d. approximate to 4.0 kpc, Both clusters are in the Galactic Bulge. The photometries attain the main sequence turnoff regions, and a discussion of ages is given as compared to other bulge and halo globular clusters.
