  Apparently if you could get up in the mountains it was visible as far south as San Diego last night (https://www.instagram.com/reel/C60uGNiuf1y/?igsh=MzRlODBiNWFlZA== https://www.instagram.com/reel/C60uGNiuf1y/?igsh=MzRlODBiNWF...) unfortunately too cloudy for most others in the area to witness

  It is cloudy here in Texas (so, a little far south also). Do the GOES satellite images show aurora?

  So this hit a K-Index of 9, which someone mentioned yesterday was around the same as the Carrington Event. Is this the only relevant metric for measuring the severity of such an event? If so, have we just weathered a storm equivalent to Carrington, without much issue?

    K-Index is more like (as someone else smartly said) a kind of heuristic subjective measure like a "Cat 5 Hurricane" Some more illuminating measurements are: Carrington: Dst -1000 from an X80 flare and CME May 2024 Event: Dst -250 from multiple up to X3.98 flares (and CMEs)
