[quote:Anonymous Coward 46621218:MV8xMzgyOTUyXzQwMTQxMDc1XzgzNDI1NDU1] [quote:#Geomagnetic_Storm#:MV8xMzgyOTUyXzQwMTM5MDEzXzRCRUZBMjE5] How exactly will we know when the poles flip? Is there an indicator of some sort? [/quote] What happens during a reversal? What do we see at the Earth's surface? As above, we have limited evidence from geological measurements about the patterns of change in the magnetic field during a reversal. We might expect to see, based on models of the field run on supercomputers, a far more complicated field pattern at the Earth's surface, with perhaps more than one North and South pole at any given time. We might also see the poles 'wandering' with time from their current positions towards and across the equator. The overall strength of the field, anywhere on the Earth, may be no more than a tenth of its strength now. http://www.geomag.bgs.ac.uk/education/reversals.html Sun Poles Passing through more often could cause more turbulent space weather, potentially leading to disruptions in satellite transmissions and telecommunications equipment. On the other hand, the current sheet also blocks high-energy cosmic rays that arrive from other areas of the galaxy, so a more wavy sheet could provide satellites and astronauts in space more robust protection from harmful radiation. Additionally, the magnetic field reversal coincides with the maximum of other solar activity, which means a greater number of sunspots, more powerful solar flares, brighter aurorae and more frequent coronal mass ejections. Most of these events have little or no effect on Earth, but an especially powerful flare or plasma ejection aimed in the right direction could knock out Earth-based telecommunications systems. At the same time, this solar cycle has been especially weak—NASA solar physicist David Hathaway called it “wimpy” in an interview with Scientific American—so there’s not a ton to worry about with this particular reversal. http://blogs.smithsonianmag.com/science/2013/09/the-suns-magnetic-field-is-about-to-reverse/ some down time reading wishing everyone a great day :hf: [/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!
