This was unexpected. The Earth experienced a strong, level three geomagnetic storm last night, jacking up the KP Index to a level 7. NOAA, NASA, the ESA and IPS in Australia all failed to predict this. The reason this was so unusual is that the solar wind speed peaked at only around 500 kps, which is stronger than ambient solar wind but much weaker than a typical CME (coronal mass ejection).
