Quiet Sun every 11 years or so, so it is not surprising that we now have a very inactive time he coronal mass ejections and sun spots. It is a natural cycle of sunspots, discovered by German astronomer Heinrich Schwabe in the mid-1800s. But this cycle of eleven years to 2012?

Sunspots are large islands of the planet’s magnetism on the surface of the sun, they are sources of sun flares, frontal mass ejections and the intensity of UV radiation. Plotting sunspot account, Schwabe saw that the peak solar activity increasingly followed by the valleys of the relative tranquility a clockwork model, also for over 200 years: the plot.

Where does this, perhaps the meaning is that the eleven years, abnormal low, which could lead, that defects heights in 2012. What is the watchword. We have on site, the cycle ends Sunday # 23, we have a 40% increase in solar activity. Thus, as we are on the peak of cycle # 24 we will see an increase of 40%? If yes, we have many problems in our hands.

Currently, as we should from the low activity, we see very little data and figures.

We see a 50-week low in solar wind pressure. Measurements of the Ulysses spacecraft show a decrease of 20% of the solar wind pressure since the mid-1990s, the lowest point since these measures began in the 1960s. The solar wind protects from galactic cosmic rays from within the solar system. Solar wind with the message, more cosmic rays are allowed, that increased risks to the health of astronauts.

We see a 12-week low in solar irradiance. Measures of NASA satellite show that the sun’s brightness is 0.02% at visible wavelengths and 6% in UV wavelengths, because solar energy to at least 1996.

We are in a 55-week low in solar energy, emissions of Radio: After the Second World War, started by astronomers, the accounts for the brightness of the sun at radio wavelengths. Discs of 10.7 cm to extend river again in the early 1950s. Radio telescopes are the registration of the variation “Radio Soleil since 1955: plot. Some researchers believe that reducing emissions of the radio is a sign of weakness in the sun in the global magnetic field.

These historic lows have sparked a debate on whether the minimum price “strange”, “extreme” or just a delay of “correction” of a number of rare intensity solar maximum. Since the Space Age began in the 1950s, solar activity was generally high. Five of the ten largest solar cycles have registration in the last 50 years. We are simply not that kind of deep silence. So what about all these anomalies?

Modern technology can not predict what comes next. Models of competition from dozens of Top-Solar-physicist not, sometimes significantly, if the solar minimum stops and the magnitude of the next solar maximum. The truth is that nobody fully understands the underlying physics of the sunspot cycle. What we know is that naxt solar maximum is approximately in December 2012.

With a bell ringing?
