A K index of 5 is not the same as a G5.
It'a G1 level storm. It's nothing.

NOAA’s Space Weather Prediction Center – the nation’s official source of warnings and alerts about space weather and its impacts on Earth – issued a warning for a strong, G3 geomagnetic storm on Earth resulting from a significant explosion from the sun’s corona Saturday morning. G-scale solar storms range from G1 (minor) to G5 (extreme). S OURCE

Yes. I know it was a G3 when the estimated Kp index reached 8 (though NOAA placed it at G2 because the Boulder K index didn't get that high). That was two days ago.
The OP is talking about a K index of 5 which occurred earlier today, much earlier.edit on 9/28/2011 by Phage because: (no reason given)
