The sun has emitted a powerful solar flare into space, releasing waves of radiation that caused a short radio blackout on Earth.

NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash at 8pm yesterday Australian EDT.

The blast did not produce a significant coronal mass ejection however, and NASA says no auroras are expected in the wake of the blast.

But according the Carter Observatory in Wellington, New Zealand, the region from where the blasts are occurring is becoming more Earth facing and any further events over the week may lead to Aurora Australis, or southern lights.
