Abstract

We consider the Earth effect in the combined Mikheyev-Smirnov-Wolfenstein analysis of the solar neutrino experiments including theoretical uncertainties. Using the time-averaged data, the allowed large-angle region extends to much smaller angles than when the Earth effect is ignored. However, the additional constraint from the Kamiokande II day-night data excludes the parameter space most sensitive to the Earth effect, leaving only a small large-angle region close to maximal mixing at 90% C.L. The nonadiabatic solution remains unaffected by the Earth effect and is still preferred.
