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) system of the smaller vessel consists of three 15MW azimuth thrusters and two 3.5MW bow thrusters instead of three fixed propeller shafts with 27MW propulsion motors and six 4.5MW rectractable transverse thrusters. The number and output of generating sets has also been reduced. The participants in the "Aurora Borealis" project are listed in the following table. Aurora Borealis (icebreaker) Aurora Borealis is a proposed European research icebreaker, comparable to the world's strongest icebreakers, planned jointly by a consortium of fifteen participant organizations and companies from ten European nations. If built, she would be the largest icebreaker ever built as well
