[quote:Hugh M Eye:MV8xMzgyOTUyXzM4ODA3NjExXzE4MzZBNEQy] Newly-numbered AR1787 gave us the M1.5 & C7.2 (told ya). Solarsoft/SDO close-up movie of M-flare: http://sdowww.lmsal.com/sdomedia/h264/2013/07/03/SSW_cutout_20130703T0655-20130703T0733_AIA_131-193-171_S14E82.mov [b]M1.5 Flare from AR1787-[/b] :7/3-Mflare: :7/3-M1.5: NOAA SWPC Update- Solar Activity [b].24 hr Summary... Solar activity increased to moderate levels. Newly-numbered Region 1787 (S13E76, Dso/beta) rotated into view and produced an M1/Sf flare at 03/0708 UTC associated with a Type II radio sweep (est. shock speed 1033 km/s) and minor discrete frequency bursts. Region 1787 also produced a C7 x-ray flare at 02/2358 UTC associated with a non-Earth-directed coronal mass ejection (CME)[/b]. Region 1785 (S11E55, Fkc/beta) produced a C7/1f flare at 02/1749 UTC as well as several B-class flares. There appeared to be gradual spot and penumbral development in the intermediate portion of Region 1785, but analysis was hampered by limb-foreshortening effects. Region 1780 (S11W85, Hrx/alpha) produced occasional B- and C-class flares as it approached the west limb. Region 1781 (N21W64, Dso/beta) gradually decayed during the period. There were no Earth-directed CMEs observed during the period. http://www.swpc.noaa.gov/ftpdir/latest/forecast_discussion.txt [b]AR1785 & 1787-[/b] :7/3-SEspots: [/quote]

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!
