The internet, public transport and telecommunications systems, base stations and power grids can be knocked out by a giant geomagnetic storm. These weather events occur when the sun ejects a large bubble of superheated fuel called plasma. This bubble is called coronal mass ejection. It usually contains a cloud of electrically conductive protons and electrons. However, it won’t be the first time. On September 1 and 2, 1859, telegraph systems around the world are said to have failed. In addition, the operators of the telegraphs received electric shocks, the telegraph paper caught fire. Now, according to a Space.com report, new scientific evidence from Antarctic ice core samples suggests that geomagnetic storms cause induced currents to flow through the power grid. This also includes transformers, relays and sensors.
These storms will not only impact the internet, but are also capable of frying delicate satellite electronics in the sky. Storms should also damage the digital and power connectors connected to them. The interruptions caused can last from three to six months.
According to the Space.com report, it’s only a matter of time before Earth is hit by another geomagnetic storm. It highlights how a storm the size of a Carrington event would be ‘extremely damaging’ to power and communications systems worldwide. It can also lead to outages that can last for weeks. Storm, if the size of the Miyake event occurs, the results would be catastrophic for the world and space weather warnings would also not be of much use.
In February, the Center of Excellence in Space Science (CESS) of the Indian Institute of Science Education and Research said that the Earth would be affected due to geomagnetic storms on the surface of the Sun. Models from the research institute indicated that there was a high probability of impact on Earth as the material was expected to pass at a speed of 21.60,000 kilometers per hour. He also said in a tweet that the impact was unlikely to be dangerous. He said geomoderate storms are likely. According to a report by spaceweather.com, the geomagnetic storms, triggered due to the coronal mass ejection, were expected to be class G1 and the explosion was expected to peak at category C3, which is considered to be in the low category.
