New Year, New Solar Cycle, New Sunspot (again!) - 1st January


2020 is upon us, and as the world wakes to a new decade, we also wake up to a new sunspot from cycle 25, no sooner had AR12753 faded this new sunspot rounded the limb in the solar southern hemisphere.  Given the southern hemisphere has this activity first, it will be interesting to see what the lag with the northern hemisphere following will be, this also leads to the likely possibility of cycle 25 being double peaked as cycle 24 was.  This asymmetry on average could numerically result in solar cycles on paper being weaker, however if both hemispherical peaks coincided this would result in the solar cycle again being numerically stronger.  We will have to see over the coming years as to how this all pans out.
