Surprise geomagnetic storm

The first geomagnetic storm of 2020 (category G1) took forecasters by
surprise this morning when a CME impact sparked bright auroras over Canada
and some northern-tier US states.

At the time of this writing, Earth's magnetic field is still reverberating
from the impact, raising the possibility of more high-latitude auroras
tonight.
