Every so often I check the following link to see what the sun is doing relative to our planet. Today I looked and was a little startled to see such a big ejection of some sort headed straight for us.

I am not a "suntard" so maybe I am not looking at this correctly. Can someone who understands this stuff explain whether the event shown in this link is a dangerous thing for Earth?
