NASA Issued Alert Data on CME and X Flare and other flares

-------------------------------------------------------------------------------​-

Understanding that X flares are much stronger and faster than other flares and there were 10 C Flares along with a M flare before the X flare and CME happened. The X flare can/does catch up with the other flares, to where they can all hit at the same time.

NASA had issued and Alert with their estimated time of arrival. They had issued it for 2:57 UTC on the 17th with a + 6 hour confidence.

That time has come and gone.

So that means now the U.S - S. America - Canada will be sun facing today and will have the most impact if any impact from the CME.

the above site is absolutely fabulous - it has everything on it for the Earth and Sun with data and information about all the various aspects. It is a place to keep bookmarked, for knowledge for those interested in Solar and Earth events. Just go to the various tabs for information - the tab about the CME arrival and expectations is under "Alerts".



Magnetosphere Stand off - is suppose to be 5.5 RE as the CME hits - from what NASA says - look at the graph above for what that means and how close the magnet field will come to the Earth in pressure.

The above link is a view/simulation of what is happening with the magnetosphere as it happens.

The NASA site linked above - also has a magnetosphere tab to see the field's reactions to the flares.

Just wanted to give this information for all those who are interested in this subject.
