The flare was accompanied by dimming in SDO/AIA 193 imagery between 31/1535-1612 UTC to the southeast of the region and between 31/1624-1705 UTC north of the region. A coronal mass ejection (CME) was visible in SOHO/LASCO C2 coronagraph imagery emerging from the southeast at approximately 31/1602 UTC followed by a second eruption to the northeast at 31/1624 UTC. [/b] Preliminary analysis suggested the eruption to the northeast was moving at approximately 400-500 km/s. Further analysis and modeling will be undertaken once sufficient coronagraph imagery becomes available. [b]Consolidation and flux emergence was evident in the intermediate portion of Region 1967 (S14E29, Fkc/beta-gamma-delta) while Region 1968 grew slightly and developed a beta-gamma configuration.[/b] http://www.swpc.noaa.gov/ftpdir/latest/forecast_discussion.txt [b]AR1968 Still Alive & Kicking-[/b] :2/1-AR1968: ....and then there was two left standing.

We have just had another huge X flare measuring at a X8.2 originating from sunspot 2673
On September 11, 2017
[

ALL flares recorded ARE Earth facing regardless of where the sunspot is located
-----------
CME FROM X9 HAS ARRIVED!
Issue Time: 2017 Sep 07 2242 UTC
WARNING: Geomagnetic Sudden Impulse expected
Valid From: 2017 Sep 07 2255 UTC
Valid To: 2017 Sep 07 2330 UTC
IP Shock Passage Observed: 2017 Sep 07 2229 UTC
On September 6th we have had 2 X flares! A X2.2 at 09:10 utc & a secend larger flare just a few hours later of X9.3 at 12:02 utc. There is a large widespread Earth directed CME associated with this latest X flare as we can see here

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!
