We present basic data on the stellar populations of the interacting galaxies PGC0029664 and PGC1188757, and their debris. Comparing B, V, R, and I deep photometry and colors obtained with the Magellan telescope with models of galaxy evolution, we estimate ages and metallicities of the stellar populations in both galaxies, as well as in those resolved regions resulting apparently from the interaction itself, namely, a bridge of material between both galaxies and the many small features observed in the spiral arms.
Result. suggest that blue and bright spots observed in the bridge are composed of recently formed stars, since they have similar blue colors to those observed in three regions embedded in the spiral arms of PGC0029664, very likely regions of recent star formation.
