The frequency of geomagnetic storms increases and decreases with the sunspot cycle. Solar flares and coronal-mass ejections tend to occur at sunspot groups. It varies with the 11-year sunspot solar cycle. This is an 11-year oscillation in sunspot number. Solar maximum and solar minimum refer to periods of maximum and minimum sunspot counts. The event occurred at a time of high sunspot activity during Solar cycle 24. The period between approximately 1645 to 1715 corresponds to the Maunder minimum in sunspot activity. The journal based its prediction on sunspot cycles. Sunspot number also changes over long periods. They are joined by Magma and Sunspot. It began in December 2008 with a smoothed minimum sunspot number of 2.2. Cannonball, Sunspot, Magma and Magik go to find them. It was also emitted from sunspot 1520. R12 is a 12 months average of daily sunspot numbers. Sam assembles a team consisting of himself, Sunspot, Magma, and Magik to go find them.
