Another year http://www.gotourspuertorico.com/ youporn As the sun arrives at the peak of its 11-year solar cycle, researchers notice the star is being unusually quite. Every 11 years, the sun undergoes a solar maximum. A solar maximum is a time during the sun's solar cycle when the number of sunspots and general solar activity should increase. During this time, the sun usually hurls out more solar flares and coronal mass ejections (CMEs). This has left researchers worried as they begin discussing the possible causes of this unusual occurrence.
