It turns out that this was a GRB or a Gamma Ray Burst which typically originate light years away from the Earth. This GRB had an origin location of RA, Dec=14h 05m 14.4s, -49d 29m 24s. These burst are some of the brightest in the universe and can last for milliseconds to minutes. This one started from about 20:02:10 and was over by 20:02:30, so less than 20 seconds long.
Although we saw this event with all of our payloads, there was much better data gathered from at least two other sources for this event; The Swift mission and Fermi Gamma Ray Busts. In fact you can go to the swift real time data site and see that they have our event, but saw it at a slightly later time.
So because the internet is full of information and I'm a sucker for educational videos from NASA and elsewhere... I give you what I found this morning.
So what are Gamma Rays? NASA Goddard has a movie about that.
At least as of 2009, the most distant object observed was a hyper-nova which produced a GRB observed at the Earth.
A GRB set to music. A bit odd, yet really kind of cool. I still like our whistler wave music better, but I might be biased.
