Re: [Geology2] SUMMARY: Geomagnetic Sudden Impulse



The farthest south the auroras were seen in the US was in Minnesota and Maine. Even if we had been fortunate enough to have them in the real south, we couldn't have seen them as cloud cover was maintained throughout the night. Europe had quite a show, as Scotland, Iceland, Finland, and Norway sported beautiful skies. In the southern hemisphere, the Aurora australis was seen in Melbourne, points in New Zealand, and in Tasmania.

This was the early warning notice before any calculations were refined sfaik.  I went through about 15-20 subsequent notices which gave scales and just looked at Aurora forecasts.   Anyone interested can back follow the link at the bottom and sign up for alerts. 
 
It went up to g-5 lvl 8 and the alert said the auroras might be seen as far south as Alabama and northern California. 
I didn't see any reports that anyone had although there were some violet/purple shots posted from Sweden.  Seems it is resolving but we are still in the high proton/ high electron reports and little or no further x-rays which get here in minutes where high energy particles take up to 36 or so hours. 

Unless this goes to something on the Carrington scale,  the largest impact for us should be aurora observing opportunities, HBO may come and go some HAM radio transmissions might be affected as the magnetosphere gets depressed closer to earth but I am not an expert there as to what you HAM types are experiencing.  Eman
