EnglishWe present CCD broad-band (UBV) photometry of the little-studied Southern open clusters Haffner 20, Haffner 21, and Trumpler 9. Located in the third Galactic quadrant (l ≃ 245°, in Puppis), they are rather young (log(age)= 7.9--8.4) and not very populated. Haffner 20 appears considerably reddened and, at 5 kpc, seems to be located in the Perseus arm; the other two clusters are much less reddened and are nearer to the Sun. FULL TEXT IN SPANISH
