(GCN 8112, Holland et al.; GCN 8113, Barthelmy et al.; GCN 8115, Palmer & Barthelmy) The repetition, the short, soft nature of the pulses, and the proximity of the source to the Galactic plane allow us to identify this source as a previously unknown Soft Gamma Repeater SGR 0501+4516.Soft Gamma-ray Repeatershttp://adsabs.harvard.edu/abs/2008ATel.1676....1B2008ATel.1676....1B
