Summary: On Sunday, April 22nd, the Interplanetary Magnetic Field near our planet turned south -- a condition that renders Earth's magnetosphere vulnerable to solar wind gusts. A G1-category geomagnetic storm persisted for much of the day on April 22nd and continued through the morning hours of the 23rd.
