Introducing Aurora B.
Yes, they were spectacular. You may have seen them, too, since last night's aurora ballet, caused by a recent geomagnetic storm, appeared as far south as Arizona. Stay tuned to the sky channel for possible upcoming light shows:
Sunspot 930 unleashed an X1.5 category flare on Dec. 14th, and the blast may have hurled a new coronal mass ejection toward Earth.If so, expect a whole new spectacle from Aurora to start tomorrow night.
Update: This latest coronal mass ejection
won't cause such a widespread display. The incoming cloud was launched yesterday by an X1-explosion above sunspot 930. The blast was not squarely Earth-directed, so the CME's impact will be a glancing one. Nevertheless, sky watchers should remain alert for auroras when the CME arrives on Dec. 16th.*The light show photographed by oldest son in November probably resulted from this solar flare.
