GRB optical transient RAPTOR movie - Way Cool

Gamma Ray Burst 051109A went off yesterday; it has a bright optical transient (z ~ 2) and was caught by lots of observatories (first published spectrum came from HET, way to go).

The RAPTOR team at Los Alamos put together a pair of movies of the data showing the fading in the first 20 minutes, going from about 15th magnitude to 17.5 (that is a factor of 10 fading in 20 minutes, the bright end is quite bright by astronomical object standards, but is almost 10,000 times fainter than can be seen by the naked eye).
