Principal Component Analysis of Ground Level Enhancement of Cosmic Ray Events

R. E. Ugwoke, A. A. Ubachukwu, J. O. Urama +3

We applied principal component analysis (PCA) to the study of five ground level enhancement (GLE) of cosmic ray (CR) events. The nature of the multivariate data involved makes PCA…

Testing the empirical relationship between Forbush decreases and cosmic ray diurnal anisotropy

Jibrin Adejoh Alhassan, Ogbonnaya Okike, Augustine Ejikeme Chukwude

The abrupt aperiodic modulation of cosmic ray (CR) flux intensity, often referred to as Forbush decrease (FD), plays a significant role in our understanding of the Sun-Earth electr…

Testing the Simultaneity of Forbush Decreases with Algorithm-Selected Forbush Event Catalogue

J. A. Alhassan, O. Okike, A. E. Chukwude

Accurate detection and precise timing of transient events such as X-ray photons, γ-ray burst, coronal mass ejections (CMEs), ground level enhancements (GLEs) and Forbush decreases…

Investigation of the Relation between Space-Weather Parameters and Forbush Decreases Automatically Selected from Moscow and Apatity Cosmic Ray Stations during Solar Cycle 23

Jibrin A. Alhassan, Ogbonnaya Okike, Augustine E. Chukwude

We present the results of an investigation of the relation between space-weather parameters and cosmic ray (CR) intensity modulation using algorithm-selected Forbush decreases (FDs…

Testing the Effect of Solar Wind Parameters and Geomagnetic Storm Indices on Galactic Cosmic Ray Flux Variation with Automated-Selected Forbush Decreases

Jibrin A. Alhassan., Ogbonnaya Okike, Augustine E. Chukwude

Forbush decrease (FD), discovered by Scott E. Forbush about 80 years ago, is reffered to as the non-repetitive short-term depression in galactic cosmic ray (GCR) flux, presumed to…
