A periodicity between 152 and 158 days was discovered in the daily number of high-energy solar flares detected by the Solar Maximum Mission (SMM) and the Geosynchronous Operational Environmental Satellites (GOES) around the maximum of solar cycle 21. In a previous work we pointed out that this periodicity had been time-coincident with a periodic emergence of magnetic flux in the form of strong magnetic fields, which suggested a causal relationship between both periodicities. Using the Mount… CONTINUE READING
