On October 1, 2011, a comet screamed into the Sun and presumably disintegrated. A few minutes later, the Sun erupted in a big blast of magnetic energy called a Coronal Mass Ejection. Are the two related?
Phil Plait show three satellite views of the comet and CME from three different angles, and describe the events. Phil Plait conclusion: it's almost certainly coincidence.
