The Indian Institute of Science Education and Research, Kolkata, expressed the possibility that the geomagnetic storm emanating from the sun can hit the earth at any time tomorrow i.e. on Thursday. Because of this, cellphone networks, satellite TV and power grids may be shut down for some time. There may also be a possibility of a black out.Know what is a geomagnetic stormAccording to a study by the US space agency NASA, there are massive massive explosions on the surface of the Sun, during which some parts release huge amounts of energy with extremely bright light called sun flares. In which a billion tons of magnetic energy is released into space at a speed of several million miles per hour, due to which some part of the outer surface of the Sun opens and energy starts coming out of this hole and it looks like a ball of fire. If this energy is released continuously for several days, then very small nuclear particles also start coming out which spread in the universe, which is called geomagnetic storm.Solar flares were released on March 28Solar flares were issued from active regions 12975 and 12976 on the Sun on March 28. The center said that since these flares collide with the Earth's magnetic field, there is a possibility of a coronal mass ejection induced moderate geomagnetic storm. The center said in a tweet that our model fit shows a very high probability of an Earth impact with a speed of between 496-607 km/s on March 31.
What would happen if a geomagnetic storm hit Earth?The effect of a geomagnetic storm hitting the Earth depends on its direction. If this storm explodes from the surface of the Sun towards the Earth, then the energy emanating from it affects there, but the chances of harming people are negligible. According to scientists, the Earth's magnetic field protects ordinary people from the radiation emitted from the sun, but still it affects some parts. Magnetic forces emanating from the Earth's womb, which form a shield around the atmosphere, which reduces its radiation to a great extent.A halo CME initiated on the Sun on 28 March. Our model fit indicates a very high probability of Earth impact on 31 March with speeds ranging between 496-607 km/s. Possibility of CME induced moderate geomagnetic storms exist.
