Abstract
We present the continuous daily electron and positron spectra over 12.5 years from 1 to 42 GV. The detailed time dependence measurements of these fluxes covering the major portion of solar cycle 24 and the first part of solar cycle 25 reveal variations on different timescales and rigidities associated to the solar activity. The simultaneous measurement of the electron and positron fluxes and the comparison with the proton flux over an extended time period offers a unique way to study charge-sign- and mass-dependent solar modulation
effects at different timescales and provides critical information to the understanding of the propagation of charged particles in the heliosphere.
