This is one huge CME, it happened yesterday. Fortunately this is not headed towards earth.
A few days ago I posted on why this could not be Elenin, it turns out that a year ago Mercury moved passed the same place. Hence I thought this was Mercury and so did a lot of other people.
Mr Cometwatch has some interesting videos and he explains why this is not Mercury. He has some good points as well.
Some people believe this is Elenin. You got Pleiades on the left there in the upper right corner of the circle. The theory of the giant plate near the sun is that it is Elenin. This is also where Mercury is supposed to be. So which is it?
Update: Ok, someone said this is actually Venus. So the many theories of this being Elenin is probably wrong. Venus then or Mercury.
NASA confirmed that the UARS satellite came down somewhere in the Pacific.
