GRB 100621A was a long gamma-ray burst observed on June 21, 2010, by the Swift spacecraft. ^{[1] [2]} It is the third brightest gamma-ray burst yet observed, after GRB 221009A and GRB 130427A. However when it was discovered, it was the brightest GRB in terms of X-ray brightness. ^{[3] [4]} GRB 100621A is approximately five billion light years from Earth.
