Incoming CME, G3 geomagnetic storm watch
Saturday, 5 October 2024 12:09 UTC
The anticipated CME from the X7 solar flare has turned out to be a nothing-burger. There was no notable impact and aurora displays were confined mostly to arctic latitudes.
However, the coronal mass ejection from the X9 solar flare which was the strongest solar flare of the current Solar Cycle thus far has of course yet to arrive. The low energy protons as measured by ACE EPAM continue to rise indicating the shock wave approaching towards our planet with an impact expected in 6 to 12 hours from now which would be today between 18 UTC and midnight UTC. A strong G3 geomagnetic storm watch remains in effect for this evening and tomorrow.
