Another blank day up to 97. The article is indeed an interesting read and it starts to set out how total irradiance can effect our climate from ozone loss or production to angular momentum etc which plays such a big part in how our climate works. We have seen a 13% increase in cosmic rays over the last cycle which is down to the strength or lack of it in this cycle. The sun should never be underestimated in its influence

Now at 97 days.

It is the 98th spotless day, 3 times more than we got last year.

Expecting well over 200 in 2018

[SteveB]

Gone on to 99 day's blank

5th day in a row, activity is expected to remain low.

100 spotless days 

The sun entering another deep solar min.

Back in early Oct I doubted if we could get to 100 but thankfully we did it.

Lucky as today a tiny sunspot appeared. Now we can sit back and relax for a few days. 

[SteveB]

Lucky that we got to 100 before the spot appeared.

Hopefully nothing major & we can go back to spotless again.

Looking to get 200+ next year......

[Katrine Basso]

It is the 101th spotless day but there is a small unnumbered sunspot that may be emerging.

It is interesting that spaceweather has kind of backtracked. Yesterday they said a small sunspot is emerging indicating that today wouldn't be spotless.

[jonboy]

The fact it remains unnumbered would suggest another backtrack and we will be at 102. 11 is the lowest number for a sunspot so I don't understand why its not numbered

[jonboy]

F.10 flux below 70 again also

[Snowy L]

Yeah nice drop in the flux to 68.8

Hard to tell from the graph but it does look as though the 90 day solar flux average is at its lowest yet in this cycle.

[karyo]

It looks like we will not record another spotless day for quite a while. There is an active sunspot that will take at least until midweek to travel to the other side of the sun.

The solar flux has increased to 76.

[Katrine Basso]

The sun has gone quite again and the sun is blank again after a week of sunspot activity.  The sun spotless number this year is 102 spotless days and it is double the amount of spotless days in 2010.

[SteveB]

Hopefully we can stay blank for the rest of 2017 & go into 2018 blank as well.

2 day's blank 103 day's for 2017

Steve do you think over the next 2 or 3 years this number will grow even bigger?

I think so, no expert but I believe we are entering a grand minimum and should see  lower levels similar if not lower than 2009.

[Fozfoster]

Thanks. It’s interesting to see what happens over the next few years because the sun is the driver of our climate and existence which I think some forgot!!!

[Katrine Basso]

The last day of the year and the sun is blank again - and it is the third spotless day.  There has now been 104 spotless days in 2017.

[SteveB]

Nice to close 2017 spotless

Totally agree, hoping the global temp increases we've seen over the last 40+ years can be halted or even reversed over the next 10-15yrs helped of course by humans repairing some of the damage we have made by cleaner greener energy.

I don't believe we are entering a grand minimum such as the 'Maunder minimum' but we are entering a significant minimum which is likely to extend to until at least 2050. Given that the last few cycles where very active and greater than that seen in recorded time its is no wonder global temps reached the levels they have. I am convinced we will see global temps start to fall back which will be claimed as man's efforts reducing CO2 etc and not the sun's effects. Sunspot activity will be a lot lower than 2009 over the next 2/3 years. Seasons will become more defined but overall temps will be reduced.
