- A fierce solar storm is moving towards the Earth at a speed of 1.6 million kilometers per hour.
- It is feared that this storm may hit the Earth today, due to which there may be a power failure around the world.
- NASA has classified this flare as an X1.5-class flare.
- X-class denotes the most intense flares, while the number provides more information about its strength.
- An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
- Satellite signals can be interrupted due to this collision.
- It can also have a direct effect on radio signals, communication and weather.
- The storm can have a significant impact on a region of space dominated by Earth's magnetic field.
- It can cause interference in GPS navigation, mobile phone signals and satellite TV, current in power lines can be increased.
- Note: However, this is rarely the case because the Earth's magnetic field acts as a protective shield.
- Due to the solar storm, people living at the North or South Pole will be able to see a view of beautiful celestial lighting (auroras) at night.
- A solar storm in March 1989 caused a nine-hour blackout Hydro-Québec's electricity transmission system in Canada.
