Swift J1644+57 (also indicated as GRB 110328A when it was discovered) is the name of the event that was observed on March 28, 2011, the tidal disruption of a star by a supermassive black hole. It has been detected by the Swift Gamma-Ray Burst Mission on March 28, 2011. It occurred in the center of a small galaxy in the Draco constellation, about 3.8 billion light-years away. "This is truly different from any explosive event we have seen before," said Joshua Bloom of the University of California at Berkeley, the lead author of the study published in the June 2011 issue of Science.
