I knew that there was a huge geomagnetic storm that created large cme's but I wasn't aware the magnitude of visible auroras at my latitude of 47°N until alerts started hitting my phone: KP6, 4% overhead, 38% horizon, solar wind data pegged. Last night's show was extraordinary. This could be a once in a lifetime event for me. I'll keep watching tonight also.
