New sunspot group unleashes barrage of huge solar flares as astronomers predict two years of storms which could cause chaos on Earth
'X-class' flare is most powerful kind of solar flare
Two years of violent solar storms predicted

Solar Flare History
In modern times, the largest solar flare measured with instruments occurred on November 4, 2003. This event saturated the GOES detectors, and because of this its classification is only approximate. Initially, extrapolating the GOES curve, it was pegged at X28. Later analysis of the ionospheric effects suggested increasing this estimate to X45. This event produced the first clear evidence of a new spectral component above 100 GHz. Other large solar flares also occurred on April 2, 2001 (X20), October 28, 2003 (X17.2 & X10), September 7, 2005 (X17), February 17, 2011 (X2). and August 10, 2011 (X6.9). In 1989, during solar cycle 22 two large flares occurred on March 6 (X15) (see: March 1989 geomagnetic storm) and August 16 (X20) causing disruptions in electric grids and computer systems
So while an X4-5 can be thought of as "big", we've had bigger. I'm sure the direction of the wave is just as relevant as the energy it contains, so if these larger ones were off a bit more than this one, it could indeed be thought as a "big" one.
I was hoping for this but...

Geomagnetic Storm Watch / Full-Halo CME Incoming! The new WSA-Enlil Solar Wind Prediction is calling for a direct CME impact during the early hours of Thursday March 8th.
The expected time of arrival is between 0600-1000 UTC. This means sometime after 2am EST, we can expect the first signs of the incoming CME Plasma cloud. The solar wind is predicted to increase to over 800 km/s and Strong Geomagnetic Storming will be possible soon thereafter.
The Solar Wind Speed data from ACE is still unavailable, however as of 7:20 UTC ,
I've been watching this-
if thats true look at that speed!
