PostSubject: Sunspots    Thu Sep 15, 2011 11:53 pm

I read a news article online about huge explosions on the Sun these past two weeks. They say the Sun has been very active recently and should be putting putting on a good light show for northern observers.

I took a look at the Sun after reading this article and there were huge and many sunspots there. The most I have seen in 10yrs, I belive? If you have a a safe filter, please check it out! I'll try and take a picture.

The whole December 21, 2012 thing came up in my last club meeting. With all the activity on the sun and the recent supernovae, it kinda makes you wonder, doesn't it???

Do we really know the state of our Sun?

Well, there's never a guarantee for anything, but based on other stars of similar size on the main sequence, it's a nice, boring, stable star that is only about halfway through it's life cycle (and therefore extremely likely to continue to support life for Earth long after we're gone).

http://en.wikipedia.org/wiki/Sun#Life_cycle

If anything, the Sun has been very quiet the last couple of decades. It was much more active 50-60 years ago (though it's much more active than during the Maunder minimum, to be sure). But an uptick in activity isn't terribly surprising given typical solar variations.

Thanks Alan. But you will agree nothing like seeing one's own picture. Wink

Of course! I just check that to determine when there are good levels of sunspots visible, so I know to take a scope outside.
