Sun awakens after Hibernation

Our sun is slowly coming out of hibernation. It seems that our sun has been oversleeping during the past year. Normally our sun goes through a cycle every 11 years.
During this period the Sun’s increases activity until it reaches a peak this generally takes around 11 years. Normally our sun is a very stable star in which activity can increase or decrease. In this case for the past year the Sun has been relatively dormant.
It is expected that the sun will peak in its 11 year period about mid-2013, This particular cycle will be a modest peak.
A few days ago the Sun released a large solar flare is particularly was captured by a satellites emanating from an active sunspot region called 1092.
As far as flares go this particular outburst was not very big but it was enough to trigger an impressive coronal mass ejection or CME. The impressive outburst was captured by NASA's recently-launched Solar Dynamics Observatory.
People on both hemispheres can expect to see an increase in auroral activity with some very colourful displays.
The Sun has mellowed down in the last few days, what is interesting is that the big spot in region 1092 has been joined by a second, smaller group of sunspot (1093) that rotated into view in the last day or so.
It is possible to have a look at Sun spot activity on the sun by projecting an image from a telescope to a white background— Never try to look at the Sun with the naked eye or optical aids without using a certified safe solar filter- please do not use cheap solar filters or welding goggles!!.
The best way to view sunspots live is by accessing the SOHO website. SOHO website Link
Beware eye damage may occur if not using proper certified solar filters

Do you think that solar flares (or lack of them) have something to do with our climate, CarlCan?

Thank you for your comment.
Who need the Sun when we have certain politicians who have the Sun shine from you know where.
Ah.... Sunspot activity especially elevated activity does contribute to some aspects of climate change.
The Sun undergoes a series of changes over centuries or even millennia and can be traced back in time via ice core samples. We are entering a specific time climate change wise, this may be caused by human factors or can be just a natural cycle that we are going through.
I am not going to go into specifics about the effects of climate change, there are more factors to be considered including natural occurrences of global warming.

We are in the process of having federal elections in Australia and the B.S. is really getting to me.
