The Geomagnetic Storm Continues
I've always been hearing that solar flares and the resulting geomagnetic storms pose danger to hard drives and electronics. Is there any truth to it?<p>Recently I've been building a server room, and naturally a question of EM insulation came up. If I were to protect my servers from this, I needed to wrap the room in a grounded mesh with holes of λ in diameter. What wavelengths am I protecting against? I couldn't find an answer online, perhaps because there isn't a mechanism which could flip bits or otherwise cause potential difference across my electronics, after a coronal ejecta reaches Earth. I can imagine how charged solar wind can interact with our atmosphere and cause voltage on long stretches of cable like telegraph or electricity lines, and consumers have surge protectors for this in multiple parts of the grid.<p>Is there something that I've missed?
