Spaceweather.com is still a day behind but hopefully it will update later on today.  SILSO has it as the 4th sun spotless day, so it will take 38 days for sun spotless days to reach 200.

I was hoping that the spotless spells would get longer and longer by now but sadly not the case.

Today we have two sunspots and a solar flux of 72.

The last minimum had very long spotless periods and that's what I want to see. Without those there won't be anything special about this cycle.

not so sure, I understood that this was a less active cycle than those of the recent past anyway? as it's apparently atypical, maybe it's descent to true minimum is also atypical, it's still descending more rapidly than previous cycles have done and the jury's out as to how active SC 25 will be...

Will be a good watch anyway!

It is, as can be seen by the gradient of the green line here:

Good luck to anyone predicting how short or long this minimum will be.🤔

A large coronal hole to be earthfacing in a couple of days.  Should be a very good aurora show with a full moon too.  Could see an interesting jetstream profile and looking forward see what effect it may have.  We could see a stronger sharper ridge with more intense northerly or will we see the HP over us before retrogressing holding and being stronger and more ‘stubborn’?  

 HOLE IN THE SUN'S ATMOSPHERE: An irregular hole in the sun's atmosphere is turning to face Earth, spewing a ragged stream of solar wind toward our planet. Estimated time of arrival: Oct. 24. NASA's Solar Dynamics Observatory took this false-color UV image of the structure on Oct. 20th:

Displays won't be great what with a full moon.

Hi all, is there a page I can visit to access breakdown of years with low solar activity or solar activity in general (back to around early 20th century). Seen many images on Google but each giving different data on this. Thanks.

I think this year we could reach 208 sun spotless days.

I am sorry for the late reply but I wonder if this can help.
