Earth-directed coronal mass ejection expected

A coronal mass ejection (CME) is heading toward Earth and it could deliver a glancing blow to our planet's magnetic field on Sept. 22th around 23:00 UT. There are no large coronal holes on the Earth-facing side of the sun. High-latitude sky watchers should be alert for auroras when the CME arrives. (SpaceWeather)

Solar activity has been low with only low level C-Class activity taking place since the C9.5 Flare early on Tuesday. The Solar X-Ray background levels are hovering near the C1 level. There will remain the chance for an isolated M-Class flare. Another sunspot group is hiding on the eastern limb and will soon begin to rotate into view. (SolarHam)
