The Aurora Named STEVE

The video discusses a unique auroral phenomenon named Steve, characterized by a narrow purple arc and green features. Initially a mystery, Steve was observed by scientists and enthusiasts, leading to new insights into auroral activities. Satellite data from ESA's Swarm revealed strong particle flows in the ionosphere associated with Steve. This discovery is significant as it allows more people to observe and understand auroras, especially in southern regions, enhancing our knowledge of sub-auroral regions.

What is the unique feature of Steve that distinguishes it from most auroras?

• It is a bright blue circle.

• It has a narrow purple arc with green features.

• It is a wide red arc.

• It appears only during the day.

What does the presence of green features in Steve suggest?

• There is a high level of solar radiation.

• There is a lack of atmospheric particles.

• There is plasma physics occurring.

• There is a strong magnetic field.

Which satellite provided important observations about Steve?

• Hubble Space Telescope

• Voyager 1

• ESA's Swarm

• International Space Station

Why is Steve considered important for scientific research?
