The CHOOZ experiment has measured the antineutrino flux at about 1 km from two nuclear reactors to search for possible <(nu)over bar>(e)--><(nu)over bar>(x) oscillations with mass-squared differences as low as 10(-3) eV(2) for full mixing. We show that the analysis of the similar to 2700 <(nu)over bar>(e) events, collected by our liquid scintillation detector, locates the antineutrino source within a cone of half-aperture approximate to 18 degrees at the 68% C.L. We discuss the implications of this result for locating a supernova explosion.
