A short time with clear skies today.  The Sun remains spotless for another day.  The pores visible yesterday in the Continuum image have decayed and are gone.  But the region as well as the two in the Southern hemisphere are still visible in Ha and CaK.  A little prominence activity was observed at the SE limb.  For the rest the Sun seems quiet.
