The northern lights, or aurora borealis, the dancing waves of light that have captivated people for millennia, will be visible in several U.S. states between Wednesday (12) and Thursday (13).
The aurora borealis can be seen in parts of Washington, Idaho, Vermont, Wyoming, New Hampshire, Montana, North Dakota, South Dakota, Minnesota, Nebraska, Massachusetts, Maryland, Ohio, Wisconsin, Michigan, New York, and Maine, according to experts.What is the aurora borealis?
The aurora borealis is a phenomenon that occurs at the North Pole of the Earth. It results from the impact of solar winds with the planet’s magnetic field.
In addition to emitting light, the Sun also emits solar winds, which are filled with energy-charged subatomic particles. Called plasma, these particles cause the light phenomenon when they come into contact with the magnetic fields of the poles.
The main colors formed are green and red. Green is formed by the emission of oxygen atoms in high atmospheric layers. Red is formed by the emission of nitrogen atoms, in greater quantity, and oxygen in lower layers.How to see the aurora?
The Space Weather Prediction Center says that the best time to see the aurora is generally between 10 PM and 11 PM and 2 AM.
• You don’t need any special equipment.
• Choose a location with little light pollution.
• Get to a higher elevation, if possible.
• Check for cloud or precipitation forecasts, which can block your view.
• Scan the skies – they can appear from all directions.
