THE BREEZE FROM A PASSING CME: A CME passed close to Earth on July 1st. It did not directly strike our planet’s magnetic field. Instead, it made itself known by “snowplowing” some dense plasma in our direction. Here are the data. The near miss caused geomagnetic unrest that could develop into G1-class storming on July 2nd.
