NASA predicts that the Sun will reverse its own magnetic poles during 2012 as result of reaching the end of the current 11-year sunspot cycle.

so... what's that going to do exactly?

this is mostly to quiet my archiologist freind who believes that the reversal will either affect the planet or redirect 433 Eros somehow.

bah, damn the Mayans and their excellent calculations for making tons of people worry about some coming end of mankind.

The sun has been reversing its magnetic poles about every eleven years for as long as we have been able to measure it.

Have you ever noticed an effect?

We'll see some activity on the sun. Astronomers will get some interesting data. That's about it. Here's a page on the last time it happened:

There's no way it's going to move asteroids or cause an apocalypse.

And while the Mayans were great naked-eye astronomers, there is no evidence that they knew anything about sunspots or the solar magnetic field, and there is no evidence that they believed the turn-over in their calendar would lead to anything bad (it is not an end, anymore than 1999/2000 was the "end" of our calender).

The Sun's magnetic polarity is more superficial than one might think. In March of 2000, the north and south pole regions had the same polarity; the south pole magnetic polarity had migrated toward the equator. By May, it had returned. Then in 2001, the poles reversed polarity.

But it is still a 11 year cycle, apparently.

You might have to change your user ID to 11111011100, the way you keep that list up. ;)

Seriously, we might as well get used to it, I suspect it will only get worse over the next 5 years (think about the build-up to Planet X).

A quick, rough count from 01101001's list shows about 40 threads from 2003 on, with 15 threads so far in 2007. A low guess would be that there will be at least 100 threads through 2012, but I wouldn't be surprised at 200.

Hey, don't blame the Maya! Gibson's last movie trashed them enough. One king said his coronation day would still be celebrated in our year 4000 and something. No, blame the archeo-woos.
