According to spaceweather, this cycle is already more active than the forecasts.

Not what I wanted to read with my morning coffee

I think it might have overtaken SC24 now, too, for the same period into the cycle.  Still hope it won't be a particularly active cycle, though.

It may be more active in terms of sunspots as such, but flux hasn't been particularly high though...

Notice the adjustment is swinging negative as the orbit brings the earth closer to the sun. Relatively speaking that is!

Yes Worth keeping a look out in the North under clear sky's tonight.

CME IMPACT SPARKS GEOMAGNETIC STORM: As predicted, a CME hit Earth's magnetic field on Oct. 12th. The impact at approximately 02:30 UT sparked a G2-class geomagnetic storm. Auroras spread across northern Europe, Iceland, Canada, and multiple northern-tier US states.

In Maine, the auroras were so bright, meteorologist James Sinko was able to photograph them using nothing more than his mobile phone.

Across the border in Saskatchewan, Frank Lang used an actual camera:
