Study Of High-Speed Solar Wind Streams Events & Solar Proton Density During Solar Cycles 22 & 23.

A geomagnetic storms is a global disturbance in Earth's magnetic field usually occurred due to abnormal conditions in the interplanetary magnetic field (IMF) & solar wind plasma emissions caused by various solar phenomenon. 138 solar wind streams in solar cycle 22 & 173 solar wind streams in solar cycle 23, have been found, which are associated with proton density, observed during 1986 to 2010. We have analyzed & studied them statistically. We have found that yearly occurrences of geomagnetic streams are strongly correlated with proton density in 11-years sunspot cycle, but no significant correlation between the maximum & minimum phase of solar cycle 22 & 23 have observed
