A CME impact from a solar eruption a few days ago arrived this morning at a little after 6:00am UT creating an ongoing geomagnetic storm. This was easily detected on my magnetometer here in the UK.
If this continues to ripple through Earth's orbital path, it should be a good night for aurora watchers.
Thanks for looking.

Just got an aurorawatch UK alert now, the Kp is 7 pity it isn't dark

Wow... I'll take another look at my data to update it. Dark and clear

Re: CME Impact 12th May 2021
Here's the full event. I've added some planetary Kp index data and solar wind magnetic polarity data from NOAA to show how all of these are interrelated. As the Bz component (red line) turns south (negative) so the magnetic field carried by the solar wind plasma links up with Earth's magnetic field lines. This allows charged particles (protons and electrons) to penetrate deeper into Earth's upper atmosphere, creating a geomagnetic storm. The more negative Bz is, the greater the effect. This CME created a G3 geomagnetic storm at its peak. This is indicated using the Kp index (planetary K index) which ranges 0-9 and is a measure of geomagnetic disturbance. More information on this can be found here...https://www.swpc.noaa.gov/products/planetary-k-index
I hope you find this interesting.

Re: CME Impact 12th May 2021-UPDATED
Looks like the Aurora alert was a bit late coming at 6pm, looks like the peak was earlier at around 12-3pm. Still no good as daylight hours, would have been good for the penguins in Antarctica though

....and I’m sure they appreciated the show.
Thanks, Alexandra.
