Our space weather alert system is in level yellow, and the CME input of energy to the Earth’s magnetosphere still continues.
So, if you live in northern latitudes, go out and look for auroras tonight!
If this level of input continues, the auroras may be seen at lower latitudes, even the US/Canadian border or below.

If we go “red” the auroras will be much lower latitude.
Analysts at the Goddard Space Weather Lab say the CME impact caused a strong compression of Earth’s magnetic field, allowing the solar wind to penetrate all the way down to geosyncronous orbit for a brief period between 19:06 UT and 19:11 UT. Earth-orbiting spacecraft could have been directly exposed to solar wind plasma during that time.
Update #2: Strong ground currents have been detected in Norway.
