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.
Soft x-ray image of a solar flare on the Sun. As the magnetic energy is being released, particles, including electrons, protons, and heavy nuclei, are heated and accelerated in the solar atmosphere. The energy released during a flare is typically on the order of 1027 ergs per second. Large flares can emit up to 1032 ergs of energy.
