The Russian-American Gallium solar neutrino Experiment (SAGE) began the second phase of operation (SAGE II) in September of 1992. Monthly measurements of the integral flux of solar neutrinos have been made with 55 tonnes of gallium. The K-peak results of the first five runs of SAGE II give a capture rate of 76{sup +21}{sub {minus}18}(stat){sup +5}{sub {minus}7}(sys) SNU. Combined with the SAGE I result, the capture rate is 74{sup +13}{sub {minus}12}(stat){sup +5}{sub {minus}7}(sys) SNU. This represents only 56%--60% of the capture rate predicted by different Standard Solar Models. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
