The 11 year solar cycle has apparently peaked, but it has been one of the weakest solar maxes of the modern era. The cycle is actually 22 years because at the end of 11 years, the sun’s magnetic field flips, and then flips again 11 years later.
NASA has a video out today that explains more, and it’s important to note that some of the biggest solar storms can occur as the cycle begins to fade, so fans of the Aurora have nothing to cry about.
Oh, and if you have any thought that this has anything significant to do with the warming of the planet, see the image below.
