Now stay down!!!

What, and deprive peeps of their best last Get Out of Fail Free card?!

There will be ebbs and flows in the daily solar flux numbers, but the trend is firmly upwards.

I remain extremely sceptical that sunspots have much, if any, effect on our weather (i.e. no sunspots = cold winters) - for example 1978/9 and 1981/2 winters came at a  time of very high solar activity!

I have updated my Solar Cycle 25 progress thread aimed at radio enthusiasts - it is here:

Incidentally.. the running 27-day mean solar flux (i.e. averaged over one solar rotation ) is currently 105.8 sfu.

The running 3 month mean is 93sfu.

Hi. Bit new to this but does it bottom out. Tia

As @uncle barty says, it's overall likely to rise as we got Solar Min over 12 months ago...

It is but to be expected I suppose as we are now more than two years after solar minimum?

Aye, but hope springs eternal!

Watched these and a couple of other feeds last night for a while. 

Also seen from Scotland as reported by the BBC.

BBC Weather Watchers have shared photographs of the aurora borealis spotted in the north of Scotland.

Creeping up again!

G2-CLASS GEOMAGNETIC STORM: Surprising forecasters, on Jan 14th a crack opened in Earth's magnetic field. Solar wind poured through the gap to spark a G2-class geomagnetic storm. The timing favoured observers in Europe, where auroras spilled across the Arctic Circle as far south as Germany:
