  We investigate the possibility to observe the QCD critical point in A+A
collisions at the SPS. Guided by the QCD phase diagram expressed in
experimentally accessible variables we suggest that the process C+C at 158
GeV/n freezes out very close to the critical point. We perform an analysis of
the available preliminary experimental data for a variety of SPS processes. The
basic tool in our efforts is the reconstruction of the critical isoscalar
sector which is formed at the critical point. Our results strongly support our
proposition regarding the C+C system.
