stock here: I have always been amazed by lightning and magnetism. And would a DEW look much different, or more like a laser beam.
Apparently some lightning bolts do pulsate with multiple flashes. This is a great video showing some spectacular lightning. As our magnetic field (shield) decreases expect more lightning. Consider protecting your flammables. Like Cuba, ouch. I did not see any lightning in all the Cuba videos that I could unearth.
