A HALO CME IS COMING (UPDATED): Minor G1-class geomagnetic storms are possible during the early hours of July 27th when a faint halo CME is expected to hit Earth’s magnetic field. The storm cloud was hurled toward us on July 23rd (~1530 UT) by a complex eruption involving a C5-class solar flare in sunspot AR3376 and the liftoff of a relatively nearby magnetic filament.
