The Northern Lights could move further south in the central United States this week




According to the National Oceanic and Atmospheric Administration, the Northern Lights may be visible in the central United States this week due to a strong geomagnetic storm.

The feature, deductively called the Northern Lights, typically occurs closer to the North Pole, near Alaska and Canada .

However, the storm could push the aurora borealis further south on Thursday and Friday, and weather models predicted seeing it in parts of Pennsylvania, Iowa and Oregon.

What happens during a geomagnetic storm?


During a storm, coronal holes (dark spots on the Sun) generate strong winds which then cause coronal mass ejections, or CMEs. CMEs project plasma and fragments of the Sun's gravitational field into the climate.

The storm started on Sunday and is expected to reach G3 (G5 is the main storm strength index) on Thursday and end on Friday.

Although many CMEs are ejected from the Sun, "most are expected to have almost no effect on Earth, although about four have possible Earth-coordinated parts," NOAA said.

What is the Aurora Borealis?


The movement of the Sun is unpredictable and sometimes the declination is an area of ​​power because it can pull the attractive field of the Earth away from our planet.

In each case, like a tight rubber band, the gravitational field comes back into force, and the force of this force creates strong waves known as Alfvén waves about 80,000 miles from the first phase. As these waves approach Earth, they travel faster due to the planet's gravity.

Electrons sometimes ride these high-speed Alfvén waves, reaching speeds of up to 45 million miles per hour as they hurtle down.

“Think surfing,” said Jim Schroeder, assistant professor of physics at Wheaton College, who led the study of the cycle. "To surf, you really have to move at the right speed for the ocean wave to catch up with you and accelerate you, and we noticed that the electrons were circulating. Assuming they are moving at the correct speed relative to the wave, they will catch up and accelerate.

As the electrons enter Earth's slightly higher climate, they collide with nitrogen and oxygen particles, turning them into a buoyant state. The excited electrons eventually relax and emit the light we see as the Northern Lights.

Guidelines for viewing the Northern Lights

You don't need to worry about fancy equipment to see the Northern Lights.

  • Choose a location with minimal light pollution.
  • Reach higher altitudes whenever possible.
  • Check the indicator for fog or precipitation that may be obstructing the view.
  • Filter the air: As long as the name is north, they can appear from all directions.
