Coronal hole and a solar filament faces Earth

The M2.1 coronal mass ejection which was expected to deliver a glancing blow to our geomagnetic field seems to have missed Earth. The solar wind data does not indicate that the magnetic cloud ever passed our planet.

That said, we did have a coronal hole facing Earth and an enhanced solar wind stream is coming our way. This solar wind stream could arrive in about 48 hours from now and cause a minor G1 geomagnetic storm.

We are also keeping an eye out on a filament channel that is facing Earth right now. If it erupts within the next 48 hours, it could send a coronal mass ejection our way.
