[quote:Anonymous Coward 14733798:MV8xMzgyOTUyXzMyMjAzNTE3Xzc5OUE1NEMx] [quote:tomasgod1:MV8xMzgyOTUyXzMyMjAzMzc4X0JCRjI5MjY0] [quote:Hugh M Eye:MV8xMzgyOTUyXzMyMjAzMjQyXzcxQzg0MjhF] Howdy, TG1, great to see you, SunBro!:cheers: I'm not sure where to begin with this event. First of all, I'm somewhat surprised at the lack of "proton snow" on SOHO considering the size and direction of the CME. The Sun seems to guard its secrets very well indeed, haha. Space Weather Message Code: WARPC0 Serial Number: 65 Issue Time: 2012 Jul 13 0034 UTC [b]CANCEL WARNING: Proton 100MeV Integral Flux above 1pfu expected[/b] Cancel Serial Number: 64 Original Issue Time: 2012 Jul 12 1740 UTC [b]Comment: Conditions no longer present for warning.[/b] Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact. http://www.swpc.noaa.gov/alerts/warnings_timeline.html ... more when I gather my wits, LOL. [/quote] I have been watching SOHO for it as well. It is a shame that they missed the initial event with this equipment, as that might have helped answer some questions. It may still be on the way. The largest push of those particles is usually out in front of the CME wave. Also, those particles travel much faster and are more Earth directed when we are magnetically connected(foot Point Location) to the Sunspot Region, which in this case, we were not. [/quote] It's so nice to read you guys. Hiya Tom. It always seems to happen that when there is an event that there is missing data.:cool2: Oh are you Tom ref to the magnetic hwy. that we wernt on when flare happened. And what do you say about the cme and the bz. Thanks. [/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!
