A lecturer from the College of Scence at the University of Basra (Dr. Doha Mahmood Mansoor )participated in a conference The 14th Arabic Conference of the Arab Union for Astronomy and

Space Which was held in the University of Sharjah, United Arab Emirates

The Participation was involved lecturing research   Estimate the Transit Time of Multiple Coronal Mass Ejection Events.

The lecture aimed to study the transit time of triple events where the rst two coronal mass ejection (CME) associated with solar energetic particle events (SEP), while the third one is not. Our study about the propagation of these CMEs and their associated shocks to estimate the best acceleration equation for the transit time calculations
