"Earth's Power Grid Receives Under 20-Minute Warning for Solar Storms"

Earth may have as little as 20 minutes to prepare for a solar storm that could severely impact power grids, as solar activity is expected to peak in 2025. Long-range forecasting in this field is currently inadequate, making it challenging to predict events over a longer timeframe. Solar storms can cause physical damage, disrupt systems on the ground, harm satellites, and lead to disruptions in broadcasting and navigation. A severe solar storm could damage up to 20 transformers, result in power cuts, and even disconnect parts of the network for weeks. Concerns persist regarding the untested equipment's ability to withstand a major geomagnetic storm.
