BRACE FOR IMPACT: A CME is expected to graze Earth’s magnetic field today, Jan. 2nd. Normally, grazing impacts have little effect, but this one might be different. The CME was hurled into space by the strongest solar flare of Solar Cycle 25, an X5-class explosion on New Year’s Eve. G1-class geomagnetic storms are likely when the CME arrives.

THE FIRST AURORAS OF THE YEAR: On Jan. 1st, a crack opened in Earth’s magnetic field. Solar wind poured through the gap and fueled the first auroras of 2024. Northern lights tour guide Chris Percival photographed the display over Vesterålen, Norway:

“Our guests had a fantastic display here tonight in Arctic Norway,” says Percival. “Shortly after the Moon rose and lit up the landscape, the aurora borealis decided to make a powerful appearance.”
The “crack” was formed by the impact of a co-rotating interaction region (CIR). CIRs are transition zones between fast – and slow-moving streams of solar wind. They contain CME-like shocks that open cracks and spark strong Arctic auroras. Aurora alerts: SMS Text
