  It has been established that Coronal Mass Ejections (CMEs) may have
significant impact on terrestrial magnetic field and lead to space weather
events. In the present study, we selected several CMEs which are associated
with filament eruptions on the Sun. We attempt to identify the presence of
filament material within ICME at 1AU. We discuss how different ICMEs associated
with filaments lead to moderate or major geomagnetic activity on their arrival
at the Earth. Our study also highlights the difficulties in identifying the
filament material at 1AU within isolated and in interacting CMEs.
