Thanks, this was a very interesting article. I am a little confused however. If he saw the flare at 11:20 am in Sept. and the outburst of auroras was at dawn the next day. Let’s say 5:20 am (anyone know what time dawn was in his area on that date?), then that would indicate a lapse of around 18 hours. Plenty of time to warn people to unplug electronics, and perhaps even throw the house main switch. But then the article goes on to say that astronauts doing a space walk would only have a few minutes to get back into their capsule for safety. Are there different kinds of energy traveling at different speeds?
Thanks gleeaikin.
