Correlation of long-term cosmic-ray modulation with solar activity parameters
Caballero-Lopez, R.A.; Engelbrecht, N.E.; Richardson, J.D. (IOP Publishing, 2019)In this work, we analyze the long-term cosmic-ray modulation observed by the Hermanus neutron monitor, which is the detector with the longest cosmic-ray record, from 1957 July. For our study we use the force-field approximation ... -
Spectral index of solar cosmic-ray flux from the analysis of ground-level enhancements
Caballero-Lopez, R.A.; Moraal, H. (Elsevier, 2016)In this work we analyze the ground-level enhancement of the cosmic-ray intensity due to solar energetic particles as observed on 29 September 1989, by using two pairs of standard and lead-free neutron monitors. This enables ...
