  The radiochemical experiment in the Homestake mine was designed to measure
the solar neutrino flux through the detection of $^{37}Ar$ produced in the
reaction $\nu_e + ^{37}Cl \longrightarrow e^-+^{37}Ar$. The comparison between
this measurement and the theoretical predictions from solar models evidences a
substantial disagreement. I reanalyzed the data evidencing a bias with high
statistical significance and suggesting a new interpretation of the data.
