The first magnetic storm of August has begun
Just as forecast this morning, the final month of summer wasted no time getting started; less than an hour ago, August’s first geomagnetic storm—and the sixth of the summer—officially began. The plasma ejection reached Earth several hours ago (around 11:30 UTC), but the indices have only now risen to the level of a geomagnetic storm.
The event is unfolding exactly as predicted, both in terms of timing and intensity: the current level falls between G1 (minor) and G2 (moderate). The forecast also indicates the storm will be short-lived—lasting no more than 4–6 hours, and possibly even less. You wouldn't have time to order a tinfoil hat (unless you made one yourself), but it wouldn't help anyway—unlike electric fields, magnetic fields cannot be shielded by metal. So, the best approach is simply this.
Have a great evening, everyone.
