There is nothing new in the predictions of another solar minimum. they have been made for years to my knowledge.
What is new is that it has been picked up by the mainstream media.
I'm so glad our local star has been rediscovered!
The next thing some fools will be saying is that it has some effect on climate! As if....

Solar Minima, Earth’s rotation and Little Ice Ages in the past and in the future: The North Atlantic–European casewww.sciencedirect.com/science/article/pii/S092181811000010XNils-Axel Mörner Paleogeophysics & Geodynamics, Stockholm, Sweden Available online 25 January 2010. Abstract The past Solar Minima were linked to a general speeding up of the Earth’s rate of rotation. This affected the surface currents and southward penetration of Arctic water in the North Atlantic causing “Little Ice Ages” over northwestern Europe. At around 2040–2050 we will be in a new major Solar Minimum. It is to be expected that we will then have a new “Little Ice Age” over the Arctic and NW Europe. The mechanism proposed for the linkage of Solar activity with Earth’s rotation is the interaction of Solar Wind with the Earth’s magnetosphere; the decrease in Solar Wind at sunspot minima weakens the interaction with the magnetosphere that allows the Earth to speed up, and the increase in Solar Wind at sunspot maxima strengthens the interaction with the magnetosphere that slows down the spinning of the Earth.

Elusive Sun waves come into focus Jul 28, 2011 "A new study sheds fresh light on the Sun, potentially explaining how vast amounts of energy are transferred from its surface to its outer atmosphere, the corona. The findings could also help to explain the origins of the solar wind, which bombards the rest of the solar system with streams of charged particles......." ---- Comment: Public release date: 20-Mar-2009 University of Sheffield Scientists find solution to solar puzzle "Scientists from the University of Sheffield and Queen's University Belfast have made a unique discovery which will help us understand one of the most puzzling features of the Sun. The research has helped explain why the outside atmosphere of the Sun is actually hotter than the inner photosphere. The surface of the Sun, known as the photosphere, reaches temperatures of 5,000 degrees. It would seem logical that the temperature is lower further away from the Sun; however the outer atmosphere, known as the corona, can reach temperatures of over a million degrees.

I've found two of them, they are called the Hellfire Sisters: Sun Blasts Twin Flares The third one is shown not doing much. www.youtube.com/watch?v=Nu6wjFt_-KA"A double whammy of coronal mass ejections occurred on our star, less than 2 hours apart, on August 3rd. Solar winds may carry these super-heated particles towards Earth; a glancing blow causing auroras and possibly damaging satellites.

"Massive Solar Storm Could Cause Catastrophic Nuclear Threat in US" By IB Times Staff Reporter | August 6, 2011 5:17 AM EDT "A severe solar storm could cause global chaos, wrecking satellite communications and would take down the most important power grids in the world for a period of years. The National Oceanic and Atmospheric Administration (NOAA) forecasts four "extreme" and many "severe" solar emissions which could threaten the planet during the current decade. Nasa has warned that a peak in the sun's magnetic energy cycle and the number of sun spots or flares around 2013 could generate huge radiation levels." www.ibtimes.com/articles/193517/20110806/solar-storm-catastrophic-nuclear-threat-united-states-satellite-communications-nuclear-regulatory-co.htm

I think we should tax these solar emissions to prevent these unnatural events happening.

Physics World Early-warning system for sunspots Aug 19, 2011 "Sunspots can trigger major eruptive events on the solar surface, which can lead to widespread power outages on Earth as well as wreaking havoc on telecommunication and navigation systems. But researchers in the US say that they have developed a technique that could detect emerging sunspots a full day or two before they appear. " physicsworld.com/cws/article/news/46914

Do You use a Network Wireless Connection?Ever wondered why the connection gives varying signal strengths? [assuming you're not slap bang next to it] "Another indicator of the level of solar activity is the flux of radio emission from the Sun at a wavelength of 10.7 cm (2.8 GHz frequency). This flux has been measured daily since 1947. It is an important indicator of solar activity because it tends to follow the changes in the solar ultraviolet that influence the Earth's upper atmosphere and ionosphere. Many models of the upper atmosphere use the 10.7 cm flux (F10.7) as input to determine atmospheric densities and satellite drag. F10.7 has been shown to follow the sunspot number quite closely and similar prediction techniques can be used." Look no further, blame The Sun, them pesky spots. apart from that it says... "The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 70 in May of 2013. We are currently over two and a half years into Cycle 24. Five out of the last six months with average daily sunspot numbers above 40 has raised the predicted maximum above the 64.2 for the Cycle 14 maximum in 1907. This predicted size still make this the smallest sunspot cycle in over 100 years." solarscience.msfc.nasa.gov/predict.shtml

"Sun, the solar system's only star" "Introduction Stars are born. They take shape. They go through a turbulent adolescence, and then they live out their lives in a predictable pattern. Some have companions to provide for. Others rapidly decline and die. In some ways, stars are just like people. ..." www.astronomytoday.com/astronomy/sun.htmlComment: A tale told with an Irish story telling flavour, makes it more palatable
