On July 14th, a long-lasting M2 coronal mass ejection took place with an earthward component:
When this cloud of magnetically-charged particles reaches Earth on July 16 (late in the day UTC), it should kick off a pretty strong geomagnetic storm. I wouldn't worry about the risks of satellite failures and the electric power grid overloading (like news media loves to report). However, it could be a great opportunity to see the Northern (and Southern) Lights for latitudes where they are rare. It all depends on how the earth's magnetic field reacts to the solar wind.
