Motion of Coronal Mass Ejections

[deleted-322784]

What are the certain forces that affect coronal mass ejections

is there a site where i can have an accurate data set of what how much of these forces and when they took place

Hi ewjoey,

Coronal mass ejections (CMEs, for short) are primarily affected by gravity and electromagnetic fields. Magnetic energy (and therefore forces) are the most important. I'm not entirely sure what type of information you are looking for, but the NOAA Space Weather Prediction Center maintains datasets related to CMEs. You can access the website here:

You can learn more about CMEs here:
