Auroras may be visible from Alaska to Illinois tonight as several coronal mass ejections barrel toward Earth.
Several coronal mass ejections (CMEs) are currently hurtling toward Earth. The first expected impact was due in the early hours this morning (March 19) but appears to be running a little late.
Forecasters now say geomagnetic activity is likely to ramp up through March 19-21, with multiple CME impacts expected to trigger minor to moderate (G1 to G2) geomagnetic storms and a chance of stronger (G3) conditions, pushing the northern lights farther south than usual.
