Space Weather

Minor G1-class geomagnetic storms are possible on Jan. 19th when a CME is expected to graze Earth’s magnetic field. The CME was hurled into space on Jan. 14th by a dramatic twisting eruption in the magnetic canopy of sunspot AR3182. High latitude sky watchers should be alert for auroras when the CME arrives.
