Regions Due to Return 28 Feb to 02 Mar Nmbr Lat Lo 1670 N17 181 Wow, look at all those plages! Plages usually appear extremely bright on the EUVI images, often brighter than (non-flaring) active regions. The many large plages are what increases the total solar irradiance during maximums. AR1682 is in danger of losing its beta-gamma classification.... [b].24 hr Summary..[/b]. Solar activity was very low. Occasional B-class flares occurred early in the period. [b]Region 1682 (S18W17, Dai/beta-gamma) showed minor intermediate spot growth and some magnetic simplification, but retained a weak beta-gamma configuration.[/b] Region 1680 (S29E11, Bxo/beta) gradually decayed during the period. Region 1681 (N17E33, Cso/beta) showed no significant change during the period. New Region 1683 (S17E79, Hsx/alpha) rotated into view midway through the period. There were no Earth-directed coronal mass ejections during the period. [b]Protons Anyone?[/b] Energetic Particle -24 hr Summary... The greater than 10 MeV proton flux at geosynchronous orbit became slightly enhanced early in the period (peak flux .9 pfu at 27/0725 UTC), [b]most likely associated with the long-duration B8 x-ray event observed from beyond the west limb on 25 Feb from old Region 1678 [/b](N08, L=069). The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels. http://www.swpc.noaa.gov/ftpdir/latest/forecast_discussion.txt [/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!
