Abstract

In this paper we have reported on a comparison between space weather events that occurred around two solar cycles i.e. during period of solar cycles 23 and solar cycle 24. The Space weather events that we have considered a large number of geomagnetic storms linked with halo-CMEs (coronal mass ejections) and solar flare events. We know that coronal mass ejections and solar flares disrupt interplanetary flow of solar wind plasma and magnetic field produces disturbance into space weather which impact on the Earth’s magnetosphere resulting huge geomagnetic storms are created into space weather. We observed those occurrences of no. of halo-CMEs events and their associated solar flares into solar cycle 23 are more frequent and energetic than comparison to solar cycle 24 so their consequences occurrences of no .of geomagnetic storms into solar cycle 23 are more frequent and effective than comparison to solar cycle 24.
