description The precision measurement of the daily proton and helium fluxes will be presented. The period of observation covers 11 year solar cycle from the ascending phase through its maximum going toward its minimum. Time variations of the fluxes on different time scales associated to the solar activity are presented. Detailed time variations of fluxes and ratio will be also presented. Remarkably, below 2.4 GV a hysteresis between the helium to proton flux ratio and the helium flux was observed at greater than the 7σ level.
