In part.. the following:from the link.
“NOAA forecasters expect the CMEs to deliver a double blow separated by hours. The first CME could spark a minor G1-class geomagnetic storm late on September 1. The second CME could intensify the storm, boosting it to a moderately strong G2-class event on September 2.”
“Storms like these do no damage to power grids or satellites. They can, however, produce beautiful auroras at high latitudes. A light show is possible in Scandinavia, Iceland, Canada, and even some northern-tier U.S. states.”
