On 2020 April 28, the Galactic magnetar SGR 1935+2154 produced a millisecond-duration radio burst that was detected simultaneously at 600 MHz and 1:4 GHz. This is not the first time radio emission has been detected from a magnetar, but it is the first observed radio emission from this particular source. What makes this event compelling is that the radio burst was detected with a fluence that is approximately a million times brighter than typical magnetar radio bursts. The fluence of this burst greatly exceeds any other known radio transient in our galaxy, and might represent a Galactic analogue to the mysterious extragalactic fast radio bursts. We propose to observe SGR 1935+2154 with the EVN to detect potential afterglow emission and search for radio bursts. This will give insightful clues into the emission mechanism for such high-energy radio bursts and could lead to better understanding the origin of fast radio bursts.
