During the low point in the sun's 11-year cycle, the
field lines up with the poles, resulting in
sunspots. At the peak of the solar cycle,
sunspots tend to form. During that phase of the solar cycle, intense bursts of radiation cause
. This often occurs with coronal mass ejections, which are
from the sun.
