The temperature and flow of the sun by a fairly predictable cycle. But recently, the nearest star to Earth has been behaving. Sun regularly interact with the earth so it's important for physicians to continue to understand the sun of solar activity. Period of solar storms can disrupt satellites and power grid security. Not only that, the astronauts could be affected by the burst of radiation caused by solar storms, therefore, the experts have to obtain a complete prediction about this.
"We're watching something unusual from what we have seen over 100 years," says David Hathaway of the Marshall Space Flight Center, NASA, in Huntsville, Alaska.
In a conference, four solar physicist displays four different methods for measuring and understanding the solar cycle.
Sunspots are magnetic concentration areas which appear as black spots on the solar surface. Chronology of solar magnetic activity is related to sunspot cycles that make up the sun.
In general, the cycles last about 11 years and requires 5.5 years to move from siklum solar minimum period in which there are only a few sunspots. Furthermore, the maximum counting spots.
"Latest Cycle is an unusual condition of a minimum of the highest number with no observed sunspots researchers since 1913," says Hathaway.
Hathaway and his team of researchers called the meridional flow measurements in which the circulation of material from the polar star of the sun rotating around at the poles. Chronology is often an impact on the power cycle.
Scientists explain the changes in the structure of this channel and level of activity associated with the frequency geomagnetis minimum and maximum of a solar cycle.
In a different approach, Sushanta Tripathy from the National Solar Observatory using the frequencies of acoustic oscillations to view the characteristics of changes in solar activity cycle.
Tripathy found that changes in acoustic frequency, in most places associated with solar activity. However, during the minimum movement, she realized that the frequency of the wave that blanketed much of the sun cause this out of the path of solar activity.
Two forms of the earthquake has been detected using osilasiakustik who had never seen in the previous cycle, who led the study, Tripathy said perpanjanganan minimum between cycles 23 and 24 are not unusual.
Frank Hill, who also comes from the National Solar Observatory different approach to predict the sunspot cycle based on the solar phenomena associated with beam currents in the sun.
East-west flow of the solar surface was first discovered in 1980 and known as the torsional oscillation. Beam currents are present at a depth of at least 105 thousand kilometers beneath the surface of the sun. And Hill together with his research team are able to explain this behavior at a depth of 966 kilometers.
This shows that the flow appeared well before the level of solar activity increases. This prompted researchers to conclude the relationship several mechanisms which trigger the onset of appearance before the activity.
Meanwhile, an observation on the sun beam currents can be useful to predict the cycle time of the sun, but more complete data is needed to ensure the accuracy of this method.
In another approach, Julia Saba, from SP Systems and Goddard Space Flight Center, NASA, in Greenbelt, using X-ray and magnetic field strength indicator as a way to predict the time marker for this solar cycle.
Saba uses magnetic mapping of the sun called the synoptic charts to observe the solar cycle number 21 to 23 and 24. By evaluating the trend in the activity of X-Ray, Saba is able to predict future incidence of approximately 18 months and will be more accurate at least two months.
"In May 2010, we see the cycle 24 is clearly below the line, even though today is pretty quiet in the southern region in general," said Saba.
The method to determine early this cycle can be useful to compare the different phases of solar activity because it can be observed in adjacent, clear of Saba.
