A G3 geomagnetic storm erupted this afternoon, which I captured on my magnetometer here in the UK. Here are my data taken a 1s cadence to capture all the details.
At G3/Kp7 there's a good chance of seeing something of the aurora overnight if the activity level persists...and if the weather breaks to reveal clear skies. Of course, it could all just as easily fizzle out

Thanks for looking.
