[b].Forecast...[/b] The geomagnetic field is expected to be quiet to unsettled on day one (12 February) due to the arrival of the 09 February CME. Days two and three (13-14 February) should see a return to quiet conditions. http://www.swpc.noaa.gov/ftpdir/latest/forecast_discussion.txt Should be another 'glancing blow' as it was north of the ecliptic. Why they (NASA) forecast a 20-hour event is a puzzle. We shall see. [/quote] Thanks. That 20 hour disturbance caught my attention. [/quote]

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!
