LGS 3 presents the optical appearance of a dwarf spheroidal galaxy, but has a significant neutral hydrogen component. Photometry of its brightest stars with COSMIC at the prime focus of the Hale telescope shows a 10 (superscript 8) year old population and a 10 (superscript 10) year old population. Either we are seeing a recent burst of star formation in a dwarf spheroical galaxy, or, if intermediate age populations are also present, we are witnesing recent transition from a dwarf irregular to a dwarf spheroidal galaxy.
