Chance for auroras Friday night: Here's what you need to know
Social media is abuzz with news of auroras that may be visible across the US on Friday night. These auroras have an outside chance of making it as far south as North Georgia.nowhabersham.com
Yeah. That'll get you views here in iowa at or at similar latitudes. But for really great views.. having watched big events... I'm hoping for sustained Bz lower than -30, Bt at 40+, and sustained Kp of 9.
The show back in 04 that gave us incredible views with the thing right over our heads put out numbers like that.
I think this one has the potential to give us that.
