Solar Maximum – You Have Not Missed Out!
The sun's magnetic field changes polarity approximately every 11 years. It happens at the peak of each solar cycle as the sun's inner magnetic dynamo reorganises itself. On 06 December 2013, NASA predicted that the sun’s polarity would flip sometime in December which would herald the peak of the current Solar Cycle 24. This peak in the sun’s activity is known as the ‘Solar Maximum’.
Solar Maximum is the period during which the Northern Lights tend to be at their strongest and most frequent.
At the time of writing (30 Dec 13) and despite reports to the contrary in certain parts of the media, NASA has not yet announced that we have reached Solar Maximum.
