[ ] is a transient
astronomical radio source
An astronomical radio source is an object in outer space that emits strong radio waves. Radio emission comes from a wide variety of sources. Such objects are among the most extreme and energetic physical processes in the universe.

Murchison Widefield Array
The Murchison Widefield Array (MWA) is a joint project between an international consortium of organisations to construct and operate a low-frequency radio array. 'Widefield' refers to its very large field of view (on the order of 30 degrees ac ...

The source was active in radio for about 1 minute every 18 minutes, from January to March 2018, but has not been recorded since.

Nature of source
It seems somewhat like a Galactic Center radio transient (GCRT) except it is thought to be only about distant.[
The radio emissions were polarised (as if affected by a ]magnetic field
A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular ...
) so it may be a predicted astrophysical object called an " ultra-long period magnetar".[ ][ ]
