On the magnetic field through the Upper Centaurus-Lupus super bubble in the vicinity of the Southern Coalsack by Bhat, Ramesh, Andersson, B.

“…The Southern Coalsack is located in the interior of the Upper Centaurus-Lupus (UCL) super bubble and shows many traits that point to a much more energetic environment than might be expected from a dark, starless molecular cloud. A hot, X-ray emitting envelope surrounds the cloud, it has a very strong internal magnetic field, and its darkest core seems to be on astronomical timescales 'just about' to start forming stars. …”
