Clouds of energetic particles emitted from the sun are hurtling towards Earth. Scientists predict that a solar storm is likely to hit Earth on October 11. The US National Oceanic and Atmospheric Administration (NOAA) has issued a warning that this impact may have some impact on satellites, radio signals, and navigation systems. However, how severe will this storm be? What impact will it have on India? Let's find out.
What is a solar storm?
A huge amount of energy and tiny particles are released into space from the sun. Some of these hurtle towards Earth. When these particle clouds reach Earth, they interact with the magnetic field surrounding our planet. As a result, changes occur in the Earth's magnetic field. This development is called a 'geomagnetic storm'. Not all solar storms are of the same level. NOAA classifies their intensity into five levels.
- G1: Minor storm.
- G2: Moderate storm.
- G3: Strong storm.
- G4: Severe storm.
- G5: Extremely severe storm.
The impact is likely to increase as the number increases. However, not every solar storm causes major damage to Earth.
What could happen on October 11?
According to NOAA estimates, two large particle clouds were released from the sun on October 7 and 8. These are traveling towards Earth. Since the second cloud is moving rapidly, scientists believe that it is possible to merge with the first cloud before reaching Earth.
In the wake of the arrival of these two clouds, it has been estimated that a medium-level G2 geomagnetic storm may form on October 11. However, the intensity of the storm depends on how they are affected by the Earth's magnetic field. Therefore, he said that the current estimates cannot be considered a final decision.
Will there be an impact on satellites and the Internet?
The areas where the impact of solar storms is most likely to be seen are those close to the Earth's poles. There may be voltage changes in the electrical systems. The companies operating the satellites may have to monitor their performance and make necessary changes.
Radio signals are likely to be weakened in some areas. The accuracy of satellite-based navigation systems may also be temporarily affected. However, just by looking at the forecast of a G2 storm, it is not possible to say that the internet will be down or the power supply will be cut off worldwide.
Will there be colored lights in the sky?
During solar storms, colored lights are likely to be seen in the sky. These are called 'auroras'. These lights are formed when charged particles from the sun collide with gases in the Earth's upper atmosphere.
These phenomena are usually seen near the North and South Poles. They can also be seen at lower latitudes than usual when a geomagnetic storm is strong. The current G2 forecast should not be expected to see auroras all over India.
How dangerous is it for India?
According to the current forecast, there is no indication that the daily life of the general public in India will be affected. There is no evidence that power cuts will occur across the country or communication systems will be disrupted. Also, auroras are not expected to be seen widely in our country.
However, its intensity may change when the solar storm reaches Earth. That's why scientists are constantly monitoring space weather conditions.
Overall, although a solar storm is likely to occur on October 11, it is still unclear what impact it will have on Earth. So there is no need to worry.
