Abstract
It is well known that the arrival times of Coronal Mass Ejections (CMEs) in the vicinity of the Earth play an important role for solar terrestrial environment. It is necessary to predict the CMEs arrival time at 1 AU, for the better forecasting of space weather. Here, using LASCO halo CMEs data of 248 events observed during time period 1996–2007, we have tried to predict the arrival times as accurately as possible of full halo CMEs only. We have also studied arrival time of halo CMEs associated with type II radio bursts and X-class soft X-ray bursts, separately. In this paper we discussed about location and speed of Earth directed CMEs. The results obtained in the present investigation are discussed in the light recent scenario of CMEs understanding.
