FRB 200428
On 28 April 2020, astronomers at the Canadian Hydrogen Intensity Mapping Experiment (CHIME), reported the detection of a bright radio burst from the direction of the Galactic magnetarSGR 1935+2154 about 30,000 light years away in the Vulpeculaconstellation. The burst had a DM of 332.8 pc/cc. The STARE2 team independently detected the burst and reported that the burst had a fluence of >1.5 MJy ms, establishing the connection between this burst and FRBs at extragalactic distances. The burst was then referred to as FRB 200428. The detection is notable, as the STARE2 team claim it is the first ever FRB detected inside the Milky Way, and the first ever to be linked to a known source. That link strongly supports the idea that fast radio bursts emanate from magnetars.
