THE STORM IS NOT OVER: A #CME hit #Earth's #magnetic field on May 10th, sparking the biggest #geomagnetic #storm in almost 20 years--an extreme (category G5) event. It is subsiding now (currently category G3), but it is not over. More CMEs are expected to hit Earth's magnetic field during the next 24-48 hours, and they could push the storm back to severe or even extreme levels
