CME Impact 12th October 2021- UPDATED

Post by Carbon60 »

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.

With the uptick in activity and more to come, it’s looking very promising, Mark.

If you do manage to see the lights and record the the display as a time lapse, please make a note of the start and end times and I’ll look out for the corresponding geomagnetic data to try to coordinate visuals with data sonification.

Good luck.

Stu.

Will do Stu, at moment cloud is the theme of things. We were out and looking 12am-1am saturday night / sunday morning but nothing. We have a storm coming in tomorrow (tuesday) so we're just going to sit it out - cook food, drink wine. I'm hopeful after the low pressure has passed through the other side of the front will bring some clearer skies. Either way the camera is charged ready...

Hi Mark....

Enjoy the food and drink while you wait out the weather. Will be great to see pics if you get some activity and clear skies!

I do hope the low-pressure does remove itself from Iceland Mark. The attached image for Tuesday shows and Wednesday doesn't look much better, but hey, like the Sun, we can't control the weather, rather just try and forecast it accurately...

Best Wishes for yourselves.
Regards
Terry

Thanks guys! It was fun staying inside today - the road authority closed all the roads around us because of the wind (virtually no rain), maximum wind speed not far from us was 118mph which isn't to be sniffed at. Was fun watching all the small trees round here bend over nearly horizontal. Still going strong as I type but tomorrow will be calmer, we're off exploring again then, fingers crossed tomorrow evening will have more broken skies...
