Sunpot Cycle 24 Truly Underway... Two Good Groups Of Spots

Unlike the last couple of tiny insignificant spots that only lasted a day.. we now have couple of good groups of sunspots on the Sun ... not just the little tiny ones like before (i.e..... beginning of January).. but at least two good groups visible...and perhaps more will appear as the sun spins on its axis. Good news for shortwave propogation. We are into Cycle 24 for sure. Where we might have had doubts with the last couple of really little spots that only lasted a day.... now we need doubt no longer... Is your unquoted source sure these are from cycle 24; i.e., do they have the reversed magnetic polarity of Cycle 24 spots or the polarity of Cycle 23? Spots, per se, are not an indicator of the new cycle. A new cycle is determined by the reversed polarity of the 'new' spots... from NASA: ... long known that sunspot magnetic fields reverse polarity from cycle to cycle. ... |
