Running above 07 in percentage, we stand a good chance of breaching the top 20 spotless years.

According to spaceweather a tiny sunspot is trying to emerge. Let's hope it fails because this spotless stretch is fascinating.

Looks like Spaceweather have counted the spot, although to my eyes it looks like it gone again this morning.

Yes, this wonderful stretch is over. Ironically the solar flux is lower today than it has been for a while.

SteveB it is good news to see that Solar flux has lowered and got back to it's lower rate of 68, may this trend continue lowering.

That's good news. As you say though, was that sunspot worth counting?

Blank days really seem to be ramping up now   could we hit the 200 mark?.     also what impact will it have with the expected upcoming Positive NAO    Time will tell.

Is solar cycle 25 going to be a very weak one?

Consensus forecasts at the moment suggest that our minima will be longer and deeper than the last (the last produced the 4th, 5th and 20th most spotless years on record) but that the peak will be just a little below the last (though still well down on normal cycles).

However as alluded to earlier, there are a number of forecast methods. 

(If the theory of this Gleisenburg minimum is correct then solar cycle 26 may be a near failure).

Nice drop for the solar flux. Is this a new low for this year?

Adjusted flux is 67.9 because we've just passed aphelion. It's been lower than that on a few days this year, but not many.

There is a remnant of a decaying active region that will rotate off the west limb in the next couple of days, so here's a prediction: 65/66 adjusted flux (observed flux 63/64) by Sunday/Monday. ☀️

Given that solar flux is low then hypothetically can we get past 60% (how many days can we afford).

No update on Spaceweather.com this morning but Solarham.net and Silso have today's sun spot count as zero.
