Planetary Kp index has reached 5.0, which is NOAA level G1 (Minor geomagnetic storm). Aurora likely at high latitudes (northern-tier US states, Scotland, Scandinavia, Canada). Possible impacts: minor power grid fluctuations, minor satellite operation impacts, migratory animals affected.
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.

This is a factual snapshot, not a claim of cause and effect – researchers are divided on whether lunar, planetary or solar factors influence seismic or weather activity. It’s included so readers can track the pattern for themselves over time.
