  Recent SNO results give strong evidence that the solar neutrinos undergo the
flavor conversion. Main issue now is the identification of the mechanism of
conversion. The LMA MSW solution with $\Delta m^2 = (5 - 7) \cdot 10^{-5}$
eV$^2$, $\tan^2 \theta = 0.35 - 0.45$ looks rather plausible: it fits well the
experimental data and our new theoretical prejudices. In the LMA case, KamLAND
should see (0.5 - 0.7) reduced signal. VAC-QVO and LOW are accepted at about
$3\sigma$-level. The SMA solution is practically excluded. No sub-leading
effects produced by $U_{e3}$ and admixture of sterile neutrino have been found.
The fit becomes worse with increase of $U_{e3}$ (for LMA) and the $\nu_s$
admixture. Still (30 - 50)% presence of the sterile neutrino is allowed.
Solutions based on the neutrino spin-flip in the magnetic fields of the Sun as
well as on non-standard neutrino interactions give good fit of the data. If
KamLAND confirms LMA MSW, the spin-flip and non-standard interactions can be
considered (and will be searched for) as sub-leading effects.
