A filament of neutral hydrogen, spanning roughly 300,000 light-years, that
may have been torn out of the Magellanic
Clouds by the Milky Way Galaxy some 200
million years ago. It forms an arc in the southern sky about 150° long,
stretching from the region between the Magellanic Clouds and passing close
to the south galactic pole.
