Forbush decreases associated with intense geomagnetic storms and their relation with drastic solar features and solar wind plasma parameters during the period of 2003-2012
Abstract Sudden short-duration decreases in cosmic ray flux, known as Forbush decreases (FDs), are mainly caused by interplanetary disturbances. In this investigation, an attempts have been made to associated Forbush Read More …
H-CMEs and solar wind plasma disturbances in relation to intense geomagnetic storms during the period of 2014-2017
Abstract We have studied intense geomagnetic storms magnitude (≤-100nT) observed between 2014 and 2017 with coronal mass ejections, hard X-ray solar flaresand disturbances in solar wind plasma parameters. We have Read More …
Solar and interplanetary causes of x-class, x-ray solar flare related forbush decreases of higher magnitude in cosmic ray intensity during the period of solar cycle 23 and rising phase of solar cycle 24
Abstract Forbush decreases (Fds) of higher magnitude associated with X-Class X-ray solar flares observed during the period of solar cycle 23 and rising phase of 24 (1997-2012) have been studied Read More …
