Wow! It’s like the sun blew it’s nose off!
Question: should I wrap my hi-fi equipment in tin foil?
Speakers too?
Wouldn’t hurt, but probably the most important step is unplugging it from the power grid, since it will be the power surges that this thing might cause that do the real damage. The earth’s magnetosphere usually blunts most of the EMP effect from these things, but they can still overload power grids by induction.
