Strong Solar Storm Hits Earth - Potential Impacts

A strong solar storm began impacting Earth on Monday and is expected to continue today with reduced intensity. The storm, rated a 4 on a five-level scale, is the strongest observed since 2003, although a level 5 storm occurred in 2024. It is caused by a powerful solar flare and may affect power grids, satellite operations, and high-frequency communications. A positive outcome of the storm is the potential for spectacular aurora borealis displays in regions where the phenomenon is rare, such as parts of the US, even as far south as Alabama. Solar activity is the cause of such events. Similar solar storms have caused problems in the past, such as power outages in parts of Sweden and damage to energy infrastructure in South Africa in October 2023, during the so-called 'Halloween storm'. US weather authorities are monitoring the situation and providing updates on the storm's progress. Despite the potential disruptions, experts emphasize that such phenomena are natural and linked to the solar cycle.
