Effect on the amplitude of magnetic field component of transmitted electromagnetic wave during geomagnetic storm

Abstract

In this paper effect of geomagnetic storm on the transmitted electromagnetic wave due to solar flare event are presented. Solar eruption produced class X4.9 solar flare on 25 February -2014. Ground data at Allahabad, Uttar Pradesh dated 26, 27, 28 February-2014 and 1st March-2014 is evaluated. Earth magnetic field is suppressed during Geomagnetic storm. In the same way this effect may be seen on the transmitted electromagnetic wave. Geomagnetic storm tries to decrease the amplitude of magnetic field component of transmitted electromagnetic wave. Equations are derived and results obtained.
