Carrington-Scale Ground Magnetic Perturbations Using Realistic Solar Wind Drivers
Abstract
The 1859 Carrington event is still widely considered the largest geomagnetic storm on record, and resulted in extraordinary variations in the geomagnetic field at low-latitudes. Were such a storm to be repeated in the modern era, it would have severe consequences for grounded infrastructure. The exact mechanism behind these low-latitude variations remains uncertain, and different processes (ionosphere, magnetosphere, FACs or some combination of the three) have been suggested in the past. In this talk, we will outline our continuing efforts to recreate the ground magnetic perturbations during the Carrington Event using the Space Weather Modeling Framework. Improving upon our previous attempts at modeling storms of this magnitude, here we will outline how we drove our simulations using realistic CME statistics and dynamics. The magnetospheric conditions required to simulate low-latitude deviations such as those seen in Colaba in 1859 are also examined.
