How much time would elapse from the point of seeing the sunspot until the flare/CME actually occurs?
- superkuh 5y agoHard to say. For a "super" event the sunspot group might be noticibly big right after it appears and flare during the emergence which would mean a ~day or two warning all the way up to a long established group slowly growing over an entire rotation around the sun and coming back to flare and/or erupt ~29 days later.
- Filligree 5y agoSo, does that mean we'd have time to shut off our power grid and disconnect any long lines of metal? AIUI, it's only a problem if sufficiently long wires are actually connected to vulnerable equipment.
- superkuh 5y agoYes. But I think there'd be a lot of political/social problems with that. The solution for the grid at least is to spend the infrastructure money to put fast ground fault interrupters on all irreplacable (<months) big backbone transformers.
