Solar minimum group

[krakatoa1883]

A very small group emerged yesterday on the south hemisphere (AR12718), just few minor spots without penumbra. It is a typical solar minimum group, however observing in WL I noted in addition several faculae, small but very bright, close to the N polar region. Small signs of activity, may be indicating that something is about to happen ?

Good capture Raf, I saw this one growing on GONG today.

Hi Raf,

Very nice CaK shots, HR & FD!

Great shots, Raf. AR2718 is tiny !

Hey Raf at least it’s a spot.

I think Calcium K or H is really going to show us a lot more activity over minimum than you think (minimum is classed in WL observations). It will be fun to watch these bright areas come and go.

Thanks to all. Alexandra, you're right, I remember, decades ago, observing the sun only in WL during minimum was really boring

I observed the group again this morning through a Baader K filter, there were less spots, only three, but the main one seems to have developed a rudimentary penumbra. The cluster of faculae close to the N pole still persist, it can be barely seen in the below full disc.

That's still a cracking spot for this time in the cycle (any will do ) interesting it is trying to form penumbra, let's hope it grows.
