Charge sign dependent modulation of protons and electrons during solar cycle 22 and 23 — Johannes Marquardt, •Bernd Heber, Carlotta Jöhnk, Marlon Köberle, and Lisa Romaneehsen — Christian-Albrechts-Universität Kiel, D

The cosmic ray electron and proton flux observed with the Kiel Electron Telescope (KET) onboard the Ulysses space probe varies with solar activity as well as with heliospheric position. Ulysses’ launched in 1990 completed its mission in 2009. The KET measured the electron, proton and helium flux during the declining phase of solar cycle 22 and during the full solar cycle 23 during an A>0 and A<0-solar magnetic epoch. In this contribution we discuss the flux variation of protons/anti protons and electrons/positrons at an averaged rigidity of 2.5 GV that were corrected for spatial gradients and compare our measurements with the ones from AMS 02 showing clear signatures of charge sign dependent modulation.
