An update as to the arrival time of this CME will be added once all data has been reviewed.
The X9.3 flare is the 14th largest X flare ever recorded!
On September 4th we had 7 M flares from fast growing sunspot 2673, with at least 1 large dense Earth directed CME. This CME will arrive late in the day on Wednesday September 6th.
There is now a 25% chance for X flares over the next 24hrs & 71% chance for M flares
We have a Long Duration M2.4 Solar Flare starting
01:05 UTC July 14th 2017
There was a full halo CME observed with this solar flare. The associated CME is Earth Directed. See discussion on the last page for all updates!
