چکیده انگلیسی
We investigated the relationship of associated CME-Preflare during the solar period 1996-2010. We found 292 CME-Preflare associated events (â¼2%). Those associated events have 0-1â¯h interval time, popular events occur within half an hour before flare starting time. Post-flares-CME associated events are wider than CME-Preflare associated events. CME-Preflare associated events are ejected from the northern hemisphere during the solar cycle 23rd, while the non-associated CMEs are ejected from the southern hemisphere. Polar CME-Preflare associated events are more energetic than the equatorial events. This means that post-flare-CME associated events are more decelerated than CME-Preflare associated events, CME-Flare associated simultaneously events and other CMEs. The CME-Preflare associated events are slower than the post-flare-CME associated events, and slightly faster than non-associated CME events. Post-flare-CME associated events are in average more massive than Preflare CME associated events and all other CMEs ejected from the Sun. CME-Preflare associated has a mean average speed which is equivalent to the mean average solar wind speed approximately.
