Supernova, caught in the act

Over at BadAstronomy, Phil Plait has a write up on SN2008D, a Supernova caught in the act of exploding on January 9, 2008.   It turns out that Alicia Soderberg, an astronomer at Princeton, had SWIFT pointed at SN2007uy, and caught the X-Ray flash of SN2008D, which is something we’ve never seen before.
