SC24.com tends to be the place where news reports do make it: http://solarcycle24com.proboards.com/index.cgi?board=general&action=display&thread=479

SC24.com is Canadian based. I know this because the owner is my buddy Kevin Posted Image

Thanks for that.

The reason for the discrepancy is because there are two different counts and the objectiveness involved in measuring the tiny sun-specks. NOAA didn't count the spot in July last year but SIDC did. SIDC are the people who keep the historical record which is what is used in the link you posted.

Thanks for that info.

We have moved onto 42 spotless days.

Currently joint 8th in spotless days since 1849.

Just a quick re-link to "spotless days", to save having to trawl back through the thread. As fozi999 said (way back when we were on 28days), the September update will be interesting!

Don't want to say too much re spots etc. for fear of what might happen.......I don't want to put the old hoodoo on it! :):)

Not sure if this has been posted before (too many pages to trawl back through...)lots of stuff to digest:

43 days now according to spaceweather, or 42. Some interesting new information on spaceather showing decline in sunspot magnetic fields from 1992, with some reference to maunder minimum, and link to article.

Hope we break 92 days, i think we'd the sun would have to break this to be of significant and immediate newsworthy attention.

Lots more info here to digest, according to Prof C de Jager, the Sun isn't going to be very active for quite some time to come.

Apparently, historical accounts of Total Solar Eclipses during the Maunder made little or no reference to the visibility of the Corona. It's known from studies of other Solar type stars that coronal activity seems to wane greatly during protracted magnetic minima.

I have also read that the recent eclipse in Asia and did show a pretty much classical Solar Min corona which implies I think that for the moment at least that we are not headed into a Maunder like minimum. Hopefully that implication is wrong!!Posted Image

to be honest i dont think we can predict this minimum,

its a case of wait and see but theres plenty going on and plenty supporting a deep minimum considering where not ment to be in the deep minimum yet its very impressive indeed.

so if cycle 25 is ment to be the true minimum then it could be even more intresting,

this cycle 24 could stay this minimum right until the end no one knows for sure.

also possible that this cycle could be the deep cycle instead of cycle 25,

but its a case of wait and see.

what i have noticed is that some of the bigger orgnisations like nasa have got it wrong purely because they cant predict the unpredictable.

after all this cycle was soposed to be a maximum with above average activity well from what i can see its far from correct.

so anybody that tells me that where not going to head into a maunder style minimum,

id say you dont know that,

no one does anything is possible.

there some great posts and links futher back through this thread,

by some very impresive scientists its worth reading because most have very good opions which could well be valid.

but at the moment its very very low and not looking like its going to burst into extreme activity its a case of wait and see.

but my opion is that this is a little more than even the best scientists expected.:pardon::D

Oh I agree with you - I am simply posting some information I have seen on reading around this topicPosted Image

Wrt NASA, they have indeed not been able to predict the solar cycle pattern with any accuracy and reality has been some way from their predictions of a year and more ago that C24 would have truly kicked in by now. They predicted C24 to be an active solar cycle but now have ratcheted down those expectations with some admission that C25 would be that bit weaker still.

That might just prove to be another overstatement the way things are going - but like others, I don't want to jinx fate and wake up the sun!Posted Image

It's all very exciting isn't it?

WRT NASA and Hathaway, they must be due to update their prediction soon. How low can it go?

Hathaway has moved the goalposts at every possible opportunity. The fact of the matter is nobody knows what is going on with re: SC24, not even NASA Solar Physicists

I think they did an update fairly recently??Posted Image A quick scan of their page should say when it was.

A 6 August link here anyway

Good point, Monds...None of us knows!!

We'll all need to 'wait and see'? :pardon:

I dont think anyone is pretending to know

are they...?

No Tamara, we don't know. Neither me, you, nor anyone-else knows...If we did, we'd be God? :rofl:

On many things I agree with you, Tamara; but, on other things I don't...I cannot just 'pat you on the back' all the time, can I? When I'm discussing things on here, it's not as a moderator; it's just as someone who doesn't agree with 'everything' that everyone says. okay?

Please Tamara - if you have a 'problem' with me, PM me. I'm not an ogre??? :rofl:

Genuinely not sure what this 'agreement' business has to do with anything?Posted Image Neither expect or want a 'pat on the back' from you for anything. Hardly natural is it?

In fact, it just might be that, sometimes, no reply or comment to follow at all might be better...and much more normal . Much as most posters receive.

Back on topic ....

...that link I just placed from NASA stresses that as as yet there is nothing 'abnormal' about C24. The cycle seems to be behaving in a 'Dalton' like way from my reading of it, but again we have to wait and see. The Corona is indicated as a feature of all but the deepest min cycles - might be worth digging around to try and find out a bit more about this.

Now I'm getting on a bit - memory not what it used to be and all that - but that bit seems to contradict something I'm sure I read in early 2008. I'm sure Mr Hathaway stated then that C24 wasn't abnormal but if things hadn't picked up by January 2009 then it might start to cause some concern amongst solar physicists.

I reckon Mr Hathaway's going to need a really good chiropractor as his back must be shot to pieces with the amount of times he has shifted the goalposts!!!!

YEP! saw that shortly after came out but i had doubts, they were far too quick deciding things were picking up, they sure got that wrong!

one more week and we will have broken the [suspicious] 52 day record for this solar cycle according to spaceweather.

about half way to breaking the record of 92 spotless dating back to 1849.

I think that the statement that this behaviour of the cycle is not abnormal is due to the fact that indeed the sun does have deep minimas and so what is happening is 'normal'. However, how its behaving compared to some projections is very different...but many have forecast a deep minima to arrive...and what we have isn't a true deep minima yet...but its heading that way.
