Its not unusual for lighting to do truly mind boggling stuff, frying stuff far away while sparing things close. Not all damage is done by the strike itself, some is done by induced currents (lightning is pulsed DC) in long cable runs, and surges FROM (not TO) ground.
I've had ligntning blow the chips completly off a NIC in the server and leave EVERYTHING else in the network running. The same strike fried a motorized pencil sharpener (it started smoking) in the building next door, and harmed nothing else in the building. Mind Boggling.
Out of curiosity, did these things happen in Alaska? I wonder if there might be added phenomena or properties of lightening in areas where geomagnetic and solar effects are sometimes stronger (sometimes much stronger).
Yes, during one of exactly 4 occurrences of Lightning I've ever seen in Juneau in 30 years. Closely ringed by mountains, Juneau seldom ever gets lightning. Solar effects happen much higher than lightning if my rudimentry understanding of the atmospheric model does not fail me. -- ----------JSA--------- There are 10 kinds of people in this world, those that can read binary and those that can't. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
