[quote:NiNzrez:MV8xMzgyOTUyXzI3OTcyMzczX0QyRTkyRjYz] [quote:HMN:MV8xMzgyOTUyXzI3OTcyMjU5XzFDOENFQzg=] [quote:NiNzrez:MV8xMzgyOTUyXzI3OTcyMTU4Xzc0ODk0MDA3] [b]CHANCE OF FLARES:[/b] NOAA forecasters have upgraded the chance of X-class solar flares today to 20%. The source would be AR1339, one of the biggest sunspots in many years. The active region rotated over the sun's eastern limb two days ago and now it is turning toward Earth The flare created waves of ionization in Earth's upper atmosphere, altering the normal propagation of radio waves over Europe and the Americas. In Ireland, the flare's effect was felt even after dark. A cloud of plasma or "CME" raced away from the blast site at 1100 km/s. The CME is not heading for Earth. It is, however, heading for Mercury and Venus. Analysts at the Goddard Space Weather Lab say the [b]CME will hit Mercury on Nov. 4th around 16:14 UT[/b]. NASA's MESSENGER probe in orbit around Mercury will be monitoring the effects of the impact. [b]If the CME overwhelms Mercury's relatively weak magnetic field, it could scour material off the planet's surface creating a temporary atmosphere and adding material to Mercury's comet-like tail[/b]. The CME should hit Venus on Nov. 5th; the gossamer cloud will probably break harmlessly against the top of planet's ultra-dense atmosphere. http://spaceweather.com/ [/quote] "could scour material off the planet's surface" yikes!!

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!
