Today’s sun was very interesting.  We have been following the cycle 25 polarized regions on the Sun so far, but this was the first day where we had three cycle 25 polarized areas at the same time.  One in the Northern hemisphere and two in the Southern.  However, none of them did show any sunspots.  Here the composite image of the CaK and HMIB image from SDO.
