    • Cosmic ray modulation processes in the heliosphere 

      Vos, Etienne Eben (North-West University, 2011)
      The solar minimum of 2009 has been identified as an exceptional event with regard to cosmic ray (CR)modulation, since conditions in the heliosphere have reached unprecedented quiet levels. This unique minimum has been ...
    • Modelling charge-sign dependent modulation of cosmic rays in the heliosphere 

      Vos, Etienne Eben (North-West University (South Africa) , Potchefstroom Campus, 2016)
      The solar minimum of cycle 23/24 has seen exceptionally quiet levels of solar activity and heliospheric modulation, which resulted in the highest cosmic ray (CR) spectrum ever recorded at Earth in December 2009 by the ...
