CME Impact 12th October 2021- UPDATED

Hi everyone,

Here are my magnetometer data from the UK leading up to and including last night's predicted CME impact (see Spaceweather.com). As my data show, the main G2 level event in the early hours of the 12th (UT) was preceded by a period of geomagnetic unrest as the interplanetary magnetic field carried by the solar wind became erratic, fluctuating north and south prior to the arrival of the faster flowing, more dense and more erratic solar wind driven by the CME. I've seen some images on the internet of beautiful aurora taken from the UK. Unfortunately I've yet to see anything for myself....one day :)

If you live in an area from which such events are easily visible, I hope you had a great view.

We were talking about you, we kept getting Spaceweather alerts and I said it would give you some nice data :bow :hamster:

Good record Stu. I've seen some nice pics of aurora as result online. Same again in 2 weeks time please, we're (hopefully!) in Iceland then...

Many thanks Alexandra/Mark.

Good luck Mark. Hopefully things will continue to pick up to produce a great light show.

The event is over..... until next time (hopefully in 2 weeks for Mark).
Here it is in full from 10th through 13th.

In the end, the impact resulted in two G2 geomagnetic storms which sparked beautiful aurora down to relatively low latitudes. Hopefully more to come as cycle 25 continues to develop.

Thanks for looking.

Nice to see your record of the event Stuart.

A few clear breaks here but no aurora was visible for me.
