- •
We have taken 33 halo CME events of the current solar cycle 24 (2009–2013).
- •
We analyzed statistically the different parameters responsible for the geoeffectiveness of solar eruptions.
- •
Big flares produce high speed CME.
- •
The source location of geoeffective halo CME events exhibit N-S asymmetry.
- •
Out of these 33 halo CME events, the majority are associated with M class flares.
