dc.description.abstractIn the present paper the effect of solar flares on ion density has been studied. The ion densities have been measured for the period 1995-1998 using RPA payload of SROSS-C2 satellite. Solar flare data has been obtained from National Geophysical Data Center (NGDC) Boulder, Colorado (USA). The study indicates considerable decrease (1.2 to 2.8 times) in total ion density during flare time as compared to normal time. Out of four ion species, i.e. O+, O2+, H+ and He+, the O+ ion density is most affected by the effects of the flare as measured by SROSS–C2. There is considerable decrease in O+ ion density while O2+, H+ and He+ density show negligible change during flare time as compared to normal time. Furthermore, relation between change in ion density (∆N) as a response to change in ion temperature (∆T) during flare time and normal days has been estimated. A comparison of ion density obtained from SROSS-C2 with IRI–2012 during the flare time indicates an overestimation by IRI-2012.en_US
