Changes in polarity, although occurring over vast timescales, can impact the location and visibility of auroras, potentially affecting displays in lower latitudes like Detroit during periods of high solar activity.
Interaction with Solar Wind
The solar wind, a continuous stream of charged particles from the Sun, interacts with the geomagnetic field. When these particles encounter the field, they become guided and channeled along magnetic field lines. This channeling process concentrates the particles at the Earth's poles, where they collide with atmospheric gases, causing the emission of light, creating auroras.
Auroral Ovals and Geomagnetic Latitudes
The region where auroras are most frequent corresponds to the auroral ovals, which are shaped by the Earth's geomagnetic field. Variations in the position and shape of these ovals are dynamically connected to changes in the solar wind. The geomagnetic latitude is a key indicator of the probability of auroral displays, and lower latitudes like those surrounding Detroit are less frequently within the auroral oval. However, exceptional solar activity can extend the reach of auroral displays into lower latitudes.
Geomagnetic Storms and Their Impact
Geomagnetic storms, triggered by intense solar activity like coronal mass ejections, significantly disrupt the geomagnetic field. These disruptions lead to increased auroral activity by allowing more solar particles to penetrate further into the atmosphere. The strength of a geomagnetic storm determines the probability of auroras being observable at lower latitudes, such as near Detroit.

In conclusion, the Earth's geomagnetic field is a crucial intermediary in the interaction between the Sun and Earth's atmosphere, influencing the likelihood of auroral displays, even in locations far from the poles.
