Aurora Forecast Could Be Due to Solar Flip
Strong auroras have been forecast for the end of this week, and some of that activity could be due to changes in the sun's magnetic field.
FAIRBANKS- Strong auroras have been forecast for the end of this week, and some of that activity could be due to changes in the sun's magnetic field.
The sun will undergo a magnetic flip over the next few months. This happens every 11 years, but scientists have only been able to monitor what happens at the solar poles since the 1970s.
The sun has a magnetic field with north and south poles. In a few months, its negatively charged north pole will have a positive charge and its south pole, a negative charge. Charged particles in the magnetic field move in a constant fury because the sun is so hot, and the interaction of those particles with others in the solar system leads to auroras, among other things.
