Active sunspot AR1504 is facing Earth and hurling coronal mass ejections (CMEs) in our direction.
A fast-moving CME that left the sun on June 14th is expected to scoop up another CME already en route and deliver a double-blow to Earth's magnetic field on June 16th.
Weak-to-moderate geomagnetic storms are possible when the clouds arrive.
