The effect of the heliospheric current sheet on cosmic-ray modulation
(North-West University (South Africa), Potchefstroom Campus, 2015)
The heliospheric current sheet is a dominant feature of the heliosphere. As solar activity increases, the tilt angle of the current sheet increases, and so does the region swept out by this structure, to cover most of ...
A calibration neutron monitor for long-term cosmic ray modulation studies
(North-West University, 2006)
The propagation of high-energy cosmic rays is influenced by the time-varying heliospheric magnetic field embedded in the solar wind, and by the geomagnetic field. To penetrate through this geomagnetic field, they must ...
A GPS-based method for pressure corrections to neutron monitor data
(North-West University, 2008)
Galactic cosmic rays are high-energy particles in the heliosphere. When entering the atmosphere of earth, they interact with the nuclei of air molecules, which then cascade down to the earth's surface. The nuclear active ...
