Propagation….

NO CME, NO PROBLEM: A coronal mass ejection (CME) was expected to hit Earth’s magnetic field yesterday, May 28th, but it did not. Either the CME missed or it is still coming, moving more slowly than expected. Despite the lack of a CME, Earth’s magnetic field experienced 12 hours of geomagnetic storming (G1-class) on May 27th and 28th. A solar wind stream unrelated to the CME sparked the storm with auroras as far south as Michigan in the USA. See below. 

AURORAS IN THE USA: Marybeth Kiczenski has been waiting years to take this picture. “Finally, last night I captured Northern lights over the Mackinac Bridge in Michigan!” she says.
