Aurora effect is known as the aurora borealis or the northern lights. The former term was coined by Galileo in 1619, from the Roman goddess of the dawn and the Greek name for the north wind. The southern counterpart, the aurora australis or the southern lights, has features almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. The Aurora Australis is visible from high southern latitudes in Antarctica, Chile, Argentina, New Zealand, and Australia. A geomagnetic storm causes the auroral ovals (north and south) to expand, and bring the aurora to lower latitudes. The
Aurora Borealis (icebreaker) a slightly smaller and cheaper (less than 500-million-euro) version, "Aurora Slim", has been suggested by the Finnish engineering company Aker Arctic. The most prominent change from "Aurora Borealis" to "Aurora Slim" is that the insulated drilling rig is no longer present. The scientist have to rely on a mobile system and shallower boreholes of a few hundred metres instead of more than . She will also have only a single moon pool instead of two as in the original concept. Like the original concept, the vessel is designed to break level ice up to in thickness. However, the dynamical positioning
