Our Sun wakes up! Region 3283 launches a #solarstorm while in the Earth-strike zone. Coronagraph images confirm it's Earth-directed. Waiting for model predictions, but impact likely by midday April 24. Expect #aurora to mid-latitudes, #GPS & HF #radio issues on Earth's nightside.
What I'm dubbing the "Valentine's Day Storm" - one of the most amazing nights of auroras I've had in my life. When I saw them getting bright, I had to pull over on the side of the road - I ended up staying there the entire night because the auroras never quit!
