V725 Sagittarii (V725 Sgr) is a semiregular pulsating variable star in the constellation of Sagittarius. As recently as a century ago, it was a Population II Cepheid; its transformation was documented by Henrietta Swope beginning in 1937, and is one of the most exciting and instructive events in variable-star astronomy. [Swope, H. 1937, Harvard College Observatory Annals, 105, 26, 499] [Demers, S. 1973, Journal of the Royal Astronomical Society of Canada, 67, 19.]
