On the simultaneity of Forbush decreases: the simultaneous effects of interplanetary parameters and geomagnetic activity indices
I. O. Eya, E. U. Iyida, O. Okike +9
Forbush decreases (Fd) are transient, short-term reductions in the intensity of galactic cosmic rays that reach the Earth's surface. When this reduction is observed at multiple loc…
Analysis of ground level enhancement events of 29 September 1989; 15 April 2001 and 20 January 2005
Romanius Ejike Ugwoke, Augustine Ubachukwu, Johnson Ozoemena Urama +3
We present the results of analyses of the ground level enhancements (GLEs) of cosmic ray (CR) events of 29 September 1989; 15 April 2001 and 20 January 2005. This involve examinati…
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…
Formaldehyde and H110a observations towards 6.7 GHz methanol maser sources
Daniel. Okoh, Jarken. Esimbek, Jian. Jun. Zhou +4
Intriguing work on observations of 4.83 GHz formaldehyde (H2CO) absorptions and 4.87 GHz H110a radio recombination lines (RRLs) towards 6.7 GHz methanol (CH3OH) maser sources is pr…
Observations of microglitches in HartRAO radio pulsars
Augustine E. Chukwude, Johnson O. Urama
A detailed observation of microglitch phenomenon in relatively slow radio pulsars is presented. Our analyses for these small amplitude jumps in pulse rotation frequency () and/o…
