[quote:Anonymous Coward 19141775:MV8xMzgyOTUyXzMyMjQxNzEzXzIyRkEyQUZE] [quote:Hugh M Eye:MV8xMzgyOTUyXzMyMjQwMzEyX0VBNDhENUQy] [quote:Anonymous Coward 17338098:MV8xMzgyOTUyXzMyMjQwMTI0XzJCODJGNzRB] I am learning so much from all of you! You all are truly amazing with your knowledge! I have a few questions. Does earths magnetic field begin to weaken when we are experiencing a longer lasting geomagnetic storm? If we are experiencing a geomagnetic storm and there would be another X Flare, would that worsen the effects when the first particles reach earth in that 8 minute time frame? I am still learning so I hope I worded my questions right. [/quote] Good questions, I'll try answer but I can barely type at this point. Hopefully someone else will help out here. The first question depends on many factors. In this case, with the Bz well-south for a long period of time, I would tend to say "yes". Because of the direct connection to the solar wind plasma, more energy from the sun is charging up the ionosphere, the magneto-tail, and the radiation belts. This causes stronger aurora, magnetic disturbances, and ground currents. Usually, most of this energy is deflected by the Earth's magnetic field. Another X-flare now would probably not have any more severe effects on the surface, but a proton storm may have a bigger effect on the ionosphere which is already disturbed. Now another big CME would definitely have a stronger effect because the radiation belts are already charged up. I hope that's corrrect, lol. [/quote] :hiding: [/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!
