Has the 9th March event CME hit the earth??
The question seems to be coming up as datas from ACE satellite clearly indicates the geomagnetic sudden impulse shortly after 12PM GMT. However the Space Weather Prediction Center has not issued any Geomagnetic Sudden Impulse advisory ? The latest available on their website is

2012-03-11 15:07 UTC  Solar Radiation Storm Declining, Awaiting Geomagnetic Storm

The coronal mass ejection associated with the R2 (Moderate) Radio Blackout that occurred at 0353 UTC March 9 (10:53 p.m. EST March 8) was expected to cause more geomagnetic storming beginning early on March 11, with intensities likely to reach the G3 (Strong) level. That CME hasn’t arrived as early as predicted, so stay tuned for updates as the day progresses. The coronal mass ejection associated with the R2 (Moderate) Radio Blackout event from 1744 UTC March 10 (12:44 p.m. EST March 10) should start to affect Earth late on March 12 to early on March 13, with intensities lower than those observed with the events of last week; forecast specifics are still in work. Meanwhile, the Solar Radiation Storm continues its decay and is currently at the S1 (Minor) level. Region 1429 remains complex, but is showing signs of weakening. Updates here as conditions warrant.

This is surprising! The Magnetometer at Boulder,Colorado shows a strong variation in the H ( Northward ) component and D ( southward) component ( MAGNETIC SOUTH AND NORTH **) 

indicating that there has been an external applied,variational magnetic field which a Solar wind induced CME can generate

Further here is a gist of data available- 

Here you can observe that there is a deflection produced of maximum 22.1nT or K index of 3.1 suggesting a CME hit

Thus SSW CONFIRMS a CME hit! 

The IMF Bz vector initially had a South polarity ( 1600UT) but is turning North and hence again will affect the storming

In all, if a storming is produced then it shall not cross G1 level and definitely not G3 which I wonder why SWPC expects

Nevertheless, the CME of 10th Mar IS ALL SET TO MAKE A POWERFUL IMPACT ON EARLY PERIODS OF 13TH MARCH 2012 RESULTING IN STORMING ON 13,14TH ALSO

STAY TUNED FOR UPDATES!!
