What if the 1859 Carrington Event had occurred 100 years later?

The Carrington Event of 1859 was the largest geomagnetic storm in recorded history, caused by an intense solar flare. https://en.wikipedia.org/wiki/Carrington_Event It caused auroras, and the destruction of Telegraph lines. What would have happened, if a comparably intense solar flare had caused a comparably intense geomagnetic storms 100 years later, in 1959? Most of the industrialized world is highly electrified, although the field of electronics is still in its infancy. The transistor had only been invented 12 years earlier, there are transistors being used in large mainframe computers, and microchips are in the process of development for the Minuteman I nuclear tipped missile, for the U.S. Air Force, but no microchip based missile guidance systems have been tested in missiles yet. However, electricity is very widely in use in the U.S., Europe, Japan and Australia. And, even in the less developed world, we have a wide range of electrical applications in the major cities. So, we have radio, television, telephones, electric starters and spark plugs in automobiles, electrical sensors and controls in nuclear power plants, in airplanes, in ships at sea, and electric lighting is a virtual universal in any developed part of the world. There are only a couple of satellites in orbit at this time, of no great practical significance, so, space technology is not yet an issue. The U.S. and the U.S.S.R. are at daggers drawn during the cold war, and electrical/electronic radar systems are essential to defense against the new ballistic missile systems carrying nuclear weapons, and attack by nuclear armed bombers like the B-52. So, what happens exactly, if the Carrington Event occurs under these conditions? Is nuclear war likely? How much damage is done to the major industrialized nations, compared to the less developed world? Does this event tend to even out the discrepancies between the Industrialized World, and the less developed nations that don't have as much dependency on electric power? What effects does this event have on future developments in science and technology?
