What this means for you
Most space weather passes without anyone noticing – but events like this are exactly why we watch the data. If conditions escalate, the first things affected are GPS accuracy, shortwave radio and, in severe cases, power grids. Now is a good moment to make sure your devices are charged and you know where your backup light sources are.
We track this in real time on our Space Weather Command Center – live storm levels, aurora maps and official NOAA alerts, explained in plain English.
