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.

Eclipses occur in groups of two or three within an eclipse season which lasts for 36 days. During this time any Full or New Moons occur as Lunar and Solar Eclipses respectively. An eclipse season occurs while the Sun is within eighteen degrees of one of the Moonâs Nodes, that is the points on the Moonâs orbital path where it crosses the path of the Sun. Eclipse seasons arise every six months. Eclipses are us!
