The recent X9.3 solar flare produced a significant coronal mass ejection which sped across the void at >700 km/s slamming into Earth's magnetosphere at midnight 7th/8th September. This was followed 12 hrs later with a second wave. Both were significantly geoeffective, each separately creating a G4 solar storm with a planetary K-index (Kp) of magnitude 8 (severe) on a 0-9 scale http://www.spaceweather.com/glossary/kp.html.
The impacts produced significant responses on my magnetometer here in the UK as can be seen below, although, owing to a technical glitch I missed the initial pulse (such is the law of Murphy), but my computer was up and running to capture the second wave yesterday. This is the largest geomagnetic storm event I've recorded!
Thanks for looking.

Re: Geomagnetic G4 Solar Storm
Nice one!! I caught the data as well here is the raw of both hits.

Excellent! Nice capture.
Looks like it's working well.

Great data all round!!!

Stu I bet I can imagine the words coming out when you found the technical glitch missed the huge initial pulse

Re: Geomagnetic G4 Solar Storm
Absolutely, Alexandra. I was so mad. I took the data on the day of the X9.3 flare and for some reason the system locked up without me realising until it was too late! Just my luck.
Still, in the grand scheme of things (Irma and all that), losing a bit of data is trivial. Annoying, nevertheless and you're right about the expletives
