Solar Transients disturbing the Terrestrial Magnetic Environment at Higher Latitudes
Geomagnetic field variations during five major Solar Energetic Particle (SEP) events of solar cycle 23 have been investigated in the present study. The SEP events of 01 oct 2001, 04 Nov 2001, 21 Apr 2002 and 14 May 2005 have been selected to study the geomagnetic field variations at two high-latitud...

Geomagnetic field variations during five major Solar Energetic Particle (SEP) events of solar cycle 23 have been investigated in the present study. The SEP events of 01 oct 2001, 04 Nov 2001, 21 Apr 2002 and 14 May 2005 have been selected to study the geomagnetic field variations at two high-latitude stations, Thule and Resolute Bay of the northern polar cap. We have used the GOES protn flux in seven different energy channels. All the proton events were associated with geoeffective or Earth directed CMEs that caused intense geomagnetic storms in response to geospace. We have taken high-latitude indices, AE and PC, under consideration and found fairly good correlation of thees with the ground magnetic field records during the five proton events.
