X1 flare and possible Earth-directed CME?

Active region AR2017 on the Sun has just produced an X1 class solar flare.  Here it is in ultraviolet, overwhelming SDO’s instrument:

sdo-uv-x1

It’s too early to say if this will produce auroras on Earth, but it’s a good bet, and on the Earth-facing side of the Sun, it might be geoeffective.  Here’s hoping.  😉  The equinox is a prime time for auroras, and we’re only a week after it now, so if this does produce, we could get a nice show.
