We derive a lower limit on the Beryllium neutrino flux on earth, Φ(Be)min = 1⋅ 109 cm-2 s-1, in the absence of oscillations, by using helioseismic data, the B-neutrino flux measured by Superkamiokande and the hydrogen abundance at the solar center predicted by Standard Solar Model (SSM) calculations. We emphasize that this abundance is the only result of SSMs needed for getting Φ(Be)min. We also derive lower bounds for the Gallium signal, Gmin=(91 ± 3) SNU, and for the Chlorine signal, Cmin=(3.24± 0.14) SNU, which are about 3σ above their corresponding experimental values, Gexp= (72± 6) SNU and Cexp= (2.56± 0.22) SNU.
