"The bright gamma-ray burst GRB 130427A was spotted on April 27, 2013 by scientists operating the Large Area Telescope (LAT) as well as the Gamma-ray Burst Monitor (GBM) on the Fermi Gamma-ray Space Telescope. [...] Because the burst is so rare in its intensity (that we have detected so far) researchers have claimed that this is a unique time to measure photon activity at this energy level.[...] The extensive information collected from this GRB has been described as the “benchmark” which will influence all future GRB researchers." -- Gamma-Ray Burst 130427A One Of The Brightest Ever Recorded http://www.iflscience.com/space/gamma-ray-burst-130427a-one-brightest-ever-recorded -- related video: Overview Animation of Gamma-ray Burst -- related press release: Monster gamma-ray burst in our cosmic neighbourhood http://www.nbi.ku.dk/english/news/news13/monster-gamma-ray-burst-in-our-cosmic-neighbourhood -- And it's already been published in 5 papers: --- Fermi-LAT Observations of the Gamma-Ray Burst GRB 130427A http://www.sciencemag.org/content/early/2013/11/20/science.1242353.full#aff-1 --- GRB 130427A: A Nearby Ordinary Monster http://www.sciencemag.org/content/early/2013/11/20/science.1242279.full?sid=84a713d3-15ed-411f-b4b9-6d77414eeabe --- The Bright Optical Flash and Afterglow from the Gamma-Ray Burst GRB 130427A http://www.sciencemag.org/content/early/2013/11/20/science.1242316.full?sid=5c61b8dc-b6da-43e4-9199-b0ae3e1388a2 --- A reverse shock in GRB 130427A http://iopscience.iop.org/0004-637X/776/2/119/article?fromSearchPage=true --- The First Pulse of the Extremely Bright GRB 130427A: A Test Lab for Synchrotron Shocks http://www.sciencemag.org/content/early/2013/11/20/science.1242302.full?sid=84a713d3-15ed-411f-b4b9-6d77414eeabe
