[quote:Hugh M Eye:MV8xMzgyOTUyXzMzMjk5ODcxX0FBMTRDODA=] [quote:madajs:MV8xMzgyOTUyXzMzMjk5NTE0XzI0NDk4Q0RB] [quote:Hugh M Eye:MV8xMzgyOTUyXzMzMjk2NDU1XzZFODMwMzI5] No sign of any CME from the M 1.4 yet. If there was one, it would definitely be geoeffective. However there was a big flare and CME on the far side about 12 hours ago from somewhere beyond the SW limb. This CME may be the x-ray source of the slow C2.8 flare very early today. Farside eruption caught by STEREO Ahead EUVI: http://stereo.gsfc.nasa.gov/browse/2012/09/08/ahead_20120908_euvi_195_512.mpg SOHO C2 image of CME off the western limb: http://sohowww.nascom.nasa.gov//data/REPROCESSING/Completed/2012/c2/20120908/20120908_1048_c2_512.jpg [/quote] Here's the model of Hugh's farside CME http://iswa.gsfc.nasa.gov:8080/IswaSystemWebApp/iSWACygnetStreamer?timestamp=2038-01-23%2000:44:00&window=-1&cygnetId=261 [/quote] I'll throw in the CACTus details while we're at it: http://www.sidc.oma.be/cactus/out/CME0038/CME.html Note: the SEEDS website is down also....this reminds me of the "derecho storm" which shut down the Washington D.C. area a couple of months back. Seems the same websites were affected. Bad weather in the District today??? [/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!
