The Sun's Odd Behavior
gyrogeerloose writes "Most of us know about the sun's eleven-year activity cycle. However, relatively few other than scientists (and amateur radio operators) are aware that the current solar minimum has lasted much longer than expected. The last solar cycle, Cycle 24, bottomed out in 2008, and Cycle 25 should be well on its way towards maximum by now, but the sun has remained unusually quiescent with very few sunspots. While solar physicists agree that this is odd, the explanation remains elusive."
This is clear to everyone except the Denialists.
I almost know nothing on the subject, but I'm thinking the 11 year cycle was empiricaly determined. One has to wonder do we have enough data on the subject compared to the age of the sun?
All these solar power devices are using the sun up.
I don't know, you'd think a massive ball of fusion fire wouldn't need warning signs, but apparently some joker still managed to break it. For future reference, the Sun does not contain any user-servicable parts. Please try to remember this, or you will invalidate the warranty.

I see what's going on here. The Mayan were right!
On the one hand, outside the kind of geeky population represented by slashdot, I really doubt a lot of people know about the 11 year cycle. On the other hand, I've seen othee articles about the recent abnormally low period, and the subect also seems to come up frequently on the recurring global warming debate that seems to crop up in every third article. (Which isn't to say that more information about the subject isn't wanted of course.)
This Space Intentionally Left Blank
The explanation is simple: the Sun is actually getting hotter, but the climatologists, in their conspiracy to frame things like the Earth was getting warmer due to greenhouse gasses, have forged all records to make it seem like the Sun was at low activity instead. That way the warming climate is blamed on human activity.
I will consider all replies and downmods to this post as further evidence of the Anthropogenic Global Warming Conspiracy. If you disagree with me, you're obvilously a paid chill or a poor, deluded fool. Or maybe you're just an evil ecoterrorist who wants to destroy our economy despite knowing better.
Go on, conspirators! Give me your best shot!
Forget magic. Any technology distinguishable from divine power is insufficiently advanced.
because Sun was acquired by Oracle.
Actually, I think this might just be Captain Larry Ellison closing the deal with the Sun.
Mod me down, my New Earth Global Warmingist friends!
The Sun has better and more important things to do than to adhere to our primitive line of thought.
The following analogy comes to mind:

Odd, I just met a an eccentric young man with a bow tie, tweed jacket and braces. He owned a small wooden blue box (about the size of a beach hut) and he said that this was a harbinger of doom and that the sun would go out if he didn't do something about it. He dashed off with a pretty young female in tow....but it's pretty cold and overcast now, so maybe the end is nigh!
Over the past few hundred years, the solar cycle has regularly varied from as short as 9 years to as long as 14*. The tone of the summary (and the S.A. article) make this sound as if it is a new thing.

...bringing you cynical quips since 1998
If the sun missed it's last "cycle", maybe one of the "probes" used to "explore" forgot to use adequate "shielding" and now the sun is pregnant.
"Action without philosophy is a lethal weapon; philosophy without action is worthless."
Don't you know that plants have been using the Sun's energy for millions of years, no wonder there is nothing left! The solution is simple: burn the forests.
Negative moral value of force outweighs the positive value of good intentions.
When James Gosling left.
Darn, someone beat me to the punchline. So. Did anyone check to see if it's still plugged in?
No, the sun isn't having its cycle because it's pregnant. DUH.
(Also am I the only one who thought Sun as in the company?)
If you want a solar story that adds a bit more mystery to the rehash of the current solar tale in the linked article, google up Livingston and Penn about the observations that the sunspot frequency is diminishing. In the past, the solar flux would match up to the sunspot number closely. Beginning some twenty some odd years ago, this century long curve matching parted ways. To sum up the mystery, in ten years time, solar cycles will continue. It's just there won't be any more sunspots. (a little hyperbole, but not as much as you think)
One of my hobbies is meteorology and as I'm in the UK there's no shortage of discussion about the weather!
Over on the various weather forums we've been discussing the solar minimum for the past couple of years, as in the UK at least there's a strong correlation between climatic cold spells and low sunspot activity (the Little Ice Age a few hundred years ago coincided with the Maunder minimum, for example). There was another minimum in the early 1800s, again coinciding with a colder period in the UK climate. It was during this time that Charles Dickens popularised the idea of a White Christmas, something which hasn't occured in 40 years here (30 miles east of London).
The effects are pretty immediate in climating terms, with an onset of years rather than decades. Although yes, the Sun's becoming more active there's been a lot of discussion as to whether the low solar activity was responsible for the coldest winter in 17 years in England (and longer than that in Scotland).
The Sun's effect on the climate is probably beyond any numerical weather prediction models at the moment but it'd be fascinating to see what the effects would be if we were to experience a prolonged period of much lower solar activity than normal!
Combine this with simulations about how long it would take an Earth sized mass to form an cool and you can probably come up with reasonably accurate value for the age of the sun. Of course this is just off the top of my head - there may be better and more accurate techniques which geologists and astophysicists have developed.
Native Americans have long known the sun to be on an (average) FIFTEEN (15) year cycle.
They are demonstrably wrong. The data is unequivocal that the cycle has been 11 years in length for the past several hundred years. Look at the plot in this article. There is no way that this is in any way consistent with a 15 years cycle. There may be other, longer cycles which the sun goes though - certainly there are multiple cycles for Earth's ice ages - but there is no evidence whatsoever to support a 15 year cycle.
We are currently over do for the de Vries (Suess) 205-210 year cycle. Hopefully it will just be a Dalton Minimum...
I thought The Sun, as in the newspaper.
Wait. Which b'ak'tun are we in again? Time to invent an enormous stone time machine and bug out, folks. LOL.

The reason why the Sun's cycle is lasting longer than expected has been known by the astronomers and astrophysicists for many years, it's just that there is a news blackout on the subject. Have you also noticed that we have had record breaking weather around the World now for several years? Now, there is a gag order on reporting the weather records being broken. How about the Volcanoes, have you noticed the increase? I'm not just talking about Eyjafjallajoekull in Iceland, there 2 now active in Ecuador right now alone. How about the sensational (unexplained) sky swirl in Norway? Odd, don't you think? What's up with the Sink holes in the Eastern U.S. and how about the melting glaciers and pole ice? These and many more unusual Earth events are happening but the public doesn't really get to find out, as the USGS, U.S.Navy or NASA control your access to the information. Please, don't bother with the IOCC status quo pablum they've been pushing for years. Do you think that C.C. is gonna explain the Norway? The Volcanoes now? Take that out of the equation. I've been telling this story since '08, it is a highly magnetic small brown dwarf in the solar system with it's South pole pointed at the Sun for the last few years sucking out the magnetron particles and softening the Sun's normal cycle. Soon it will break free of the ecliptic, and Slashdot will be no more. Survivable though. subscribe to my newsletter to get the details. Chris Thomas.
Also am I the only one who thought Sun as in the company?
Given that the Sun logo appears along side the story, I'd imagine that at least one Slashdot editor had the same thought...
