As I write the sun is unleashing another X class flare which I believe was an X8.
The KP index is quiet and any ejecta should miss earth but we may get done radio effects
Will Irma be affected or of this too little too late?
Impact has occurred earlier than expected and sparked a G4 magnetic storm;
The debris from Wednesday’s monster X9-class solar flare reached Earth last night–and its impact was everything forecasters expected. A severe G4-class geomagnetic storm commenced, sparking auroras over Scandinavia so bright they actually stopped traffic. “I was driving home when the CME hit,” reports Jani Ylinampa of Rovaniemi, Finland. “It was such an amazing display, I really had to pull over and shoot some photos.”
***Update 4*** Tamitha Skov with the latest Space Weather report. This looks to be a big storm coming, however the UK Will probably be shrouded in cloud making viewing of any auroras nigh on impossible. https://YouTube.com/watch?v=oMAl5b5cXm0 SpaceWeather have also highlighted a third X-Flare from AR2673 ***Update 3*** Dr. Tamitha Skiv discusses the X-Flare https://YouTube.com/watch?v=ahMAY_GRxpA ***Update 2*** Ben Davidson chimes in; https://YouTube.com/watch?v=pQXu4JmbvzU Current conditions; ***Update 1*** Solar Ham write; https://youtube.com/watch?v=tGRBPx8Uj-A
A bright, fast moving halo coronal mass ejection (CME) is seen leaving the sun following the X9.3 event earlier today and does indeed have an Earth directed component. Because of the sunspots location now off center in the southwest quadrant, the bulk of the plasma cloud is traveling to the west. The Earth directed flank is still significant enough to almost make a geomagnetic storm a certainty by Friday.

On Sept. 6th at 1202 UT, sunspot AR2673 unleashed a major X9.3-class solar flare–the strongest solar flare in more than a decade. X-rays and UV radiation from the blast ionized the top of Earth’s atmosphere, causing a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean:
The explosion also produced a CME, shown here in a movie from NASA’s STEREO-A spacecraft. (The fast moving star-like object in the STEREO-A movie is the planet Mercury.) NOAA analysts are still modeling the trajectory of the CME to determine whether or not it is Earth-directed.
Many readers are asking about the historic context of this event. How epic is it? Answer: This is a decade-class flare. A list of the most powerful solar flares recorded since 1976 ranks today’s flare at #14, tied with a similar explosion in 1990.
Compared to the iconic Carrington Event of 1859, or even the more recent Halloween storms of 2003, this event is relatively mild. Modern power grids, telecommunications, and other sun sensitive technologies should weather the storm with little difficulty
It will be interesting to see if hurricane Irma’s track modifies and if the current cool wet weather, set for the British isles, changes in the days ahead.
