Solar Wind to Graze Earth ~ SpaceWeather.com ~ 21 May 2018

Doesn't matter if the Solar Winds just grazed or razed the Planet, we're feeling ALL of it, and some in real-time, too!

Minor geomagnetic unrest is possible on May 23rd when a stream of solar wind is expected to graze Earth's magnetic field. The gaseous material is flowing from a hole in the sun's atmosphere, shown here in an extreme ultraviolet image from NASA's Solar Dynamics Observatory (image above)

Because this hole is centered in the sun's northern hemisphere, the emerging stream of solar wind won't hit Earth directly. Instead, it will likely graze our planet's magnetic field--a geometry that can cause the magnetosphere to ring like a bell.

High-latitude sky watchers should be alert for auroras, especially in the southern hemisphere where deepening autumn darkness favors visibility of Southern Lights.
