Abstract
This project aims to study long term solar wind-magnetosphere coupling during HILDCAA events.In the proposed project an attempt will be made to derive a list of HILDCAAs for the period from 1957 to 2011. The time period (1957-2011) corresponds to five complete (11-year) solar cycles (19-23). The list can be utilized to study different statistical aspects of HILDCAAs, like the dependence o…
