I just watched the video. Was that a SPLAT!!! about the time the remnants of the comet would have hit?

Looks like it. Not the first time a comet has seemed to create a CME at the moment of impact. ISON is much more massive but “suppose” to miss.

I've been wondering about that, too. The eruption happened all over the Sun's surface simultaneously at the very moment the comet reached the western limb. But the Sun is 800,000 miles across, and it would take a ray of light about four seconds to travel that distance, more for any other kind of disturbance that propagated from the point of impact across the surface or through the interior of the Sun. So it must have been a coincidence. But that seems soooooooo unlikely! I hope someone can explain it because I surely cannot.
