Solar Flares: Solar Maximum Expected To Occur In May. Solar flares have been predicted to be stronger in 2013 due to the Sun reaching the peak of its 11-year cycle. A scientific panel recently noted that the Sun is currently experiencing its âdeepest minimumâ in almost 100 years. The researchers also indicated that the next solar maximum may occur in May. If expectations are accurate, solar flares which are weak now, could intensify as we head closer toward the summer months. So far in 2013, solar activity has remained relatively low, PHYS.org News reports.
Three recent solar cycles. Solar minimum is the period of least solar activity in the 11 year solar cycle of the sun. During this time, sunspot and solar flare activity diminishes, and often does not occur for days at a time. The date of the minimum is described by a smoothed average over 12 months of sunspot activity, so identifying the date of the solar minimum usually can only happen 6 months after the minimum takes place.
