About a week before the publication of this comic, on Wednesday, November 20, 2019, [https://www.cnn.com/2019/11/20/us/aurora-borealis-wednesday-trnd-scn/index.html aurora activity was visible] in the northern United States and southern Canada. |
'''Subtropical/Tropical latitudes:''' Charged particles of sufficient energy to cause auroras at this latitude are very rare and have happened on only a few occasions in recorded history, and not during the space age. A particularly strong one was the {{w|solar storm of 1859}}, which caused failure of telegraph systems all over Europe and North America and in some cases gave telegraph operators electric shocks. An event of that magnitude today would likely interfere with the functioning of electronic systems in orbit, possibly to the point of disabling them entirely, and would cause widespread damage to our now highly electrified world. | '''Subtropical/Tropical latitudes:''' Charged particles of sufficient energy to cause auroras at this latitude are very rare and have happened on only a few occasions in recorded history, and not during the space age.
