Looking at the Behind EUVI I think I see the event beginning from the Sunspot Region in the South and then sweeping North either along a Filament Channel or is possibly a cascading event similar to a Solar Tsunami...Do you know for sure that there was a Filament in that Region Hugh? I'm wondering if perhaps there was a small(ish) CH in the North/Mid-North Above the Sunspot Region that seems to have begun the event as well as a possible Filament as the eruption appears to be quite large and violent - A CH in the same Region would definitely play into helping the cascading type effect that made the Filament erupt in tandem with the Lower Sunspot Flare-up that(Imo)looks to have begun the chain of events - Are any of you also seeing the event happening from the South Up? http://stereo.gsfc.nasa.gov/browse/2012/12/20/behind_20121220_euvi_195_512.mpg .

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!
