A CME IS COMING: Yesterday, the sun launched a coronal mass ejection (CME) into space: movie. It wasn’t aimed directly at Earth. Nevertheless, we might feel its effect on March 23rd when the storm cloud is expected to deliver a glancing blow to Earth’s magnetic field.
AURORAS IN THE USA: A solar wind stream hit Earth’s magnetic field on March 20th, igniting a brief but strong G2-class geomagnetic storm. Bright auroras illuminated skies over Canada, then spilled across the border into the USA. “There was an explosion of color,” reports Greg Ash, who took this picture outside Duluth, Minnesota.
