Scientists at the Space Weather Laboratory flew into action, modeling the event to determine how close it had come to the spacecraft using data from the twin STEREO sun observers.

Enlil, who wears a crown of horns, is known for being a kind but also cruel god who sends forth disasters, including a great flood that wiped out humanity. Fortunately Messenger escaped Enlil's wrath."
