“it would have to be a high altitude burst of at least 1 megaton”

Not true. the EMP intensity difference between a 1kT, a 10kT, and a 100kT device are not that significant if detonated at the same altitude (greater than 20 miles or so)

Yep. They still get it wrong. Good to see you posting. I think both Compton and Carrington would be a bit concerned about the latest solar activity. JMHO.
