Long data: Solar storms are projected to

As Samuel Arbesman in a recent article in the long data one might think, the activities of the information in the world today, the Sun will be able to tell what it is going to do tomorrow. But the exact last centuries has given us an understanding of the predictive patterns of solar storm activity.  This collection of data and the long insights, there is no guarantee you can view only the ads that are related to yours, but it keeps running the worldwide electrical and telecommunications infrastructure.

Scientists at NASA's Marshall Space Flight Center recently posted their predictions of solar cycle 02013. This coming fall is projected to peak at the 24th 11-year sunspot cycle. While this may sound like a scary, that's really prepared for the lowest since 01906. Although the expected solar activity and its implications for this year does not violate a number of records, the source of these predictions is an exceptional example of the long-term thinking of data stretching back more than 350 years.

Since the beginning of the 18th century astronomers have consistently noted a number of spots on the Sun's sunspot observation from the star catalogue of the Chinese astronomer Gan De 364BCE records. Belgian Solar influences Data Analysis Center to provide the information on an annual basis, the monthly sunspot 01700 01750 and daily from 01874. A modern solar forecasts are created to analyze trends and to measure activity caused by the Sun, the Earth magnetic field.

NASA solar physicist, Dr. David Hathaway tells the details of:

The techniques used to predict, at least during the period and amplitude of the sunspot. Relationships have been found in the next cycle of the previous cycle, the maximum size and the activity of sunspots and the length of the preceding period of at least the size of the.

Are those who are using measurements of changes in the Earth's magnetic field and before sunspot minimum of the most reliable methods. These changes in the Earth's magnetic field is known to be caused by solar storms, but the precise links between themselves and the future of solar activity is still uncertain.

The second is a change in the level of solar activity mode at a wavelength of 10.7 cm radio radiation from the Sun (2.8 GHz frequency). This magnetic flux is measured on a daily basis since 1947. That is why Dotin solar activity has a tendency to follow the Sun's ultraviolet changes that affect the Earth's upper atmosphere and ionosphere. Many of the models used in the upper atmosphere 10.7 cm flux (F 6.6) as input to the atmospheric density and satellite drag.

To predict the behavior of the sunspot cycle is quite reliable when the cycle is well underway (about 3 years after at least sunspot number [See Hathaway, Wilson and Reichmann solar physics; 151, 177 (1994)]). Before that time, however, the projections are less reliable, but just as important. Satellite orbits and space design often require information on solar activity levels years in advance.

While many solar systems are still a mystery, the researchers are able to anticipate the working well enough for our communication satellites, and time to prepare for a powerful geomagnetic storms, which can cover the entire city.

First solar storm recorded in September was caused by the significant flaws and 01859 as far as is known, the developing countries of the world telegraph system and the northern lights as far south as the Caribbean. In recent times, less severe storm 01989 was referred to the six million Canadians without power for nine hours. Predict the next big solar event becomes so important as to predict the next hurricane in terms of our infrastructure.

In the past seriously is a clear route to a good prognosis, but the composure to collect a seemingly useless to facilitate predictions of future thinkers is worth considering. Astronomers centuries ago had concrete applications of the data, they are stored in the Sun. Fortunately, however, they took the time to carefully gathering and compiling what they could see that today, when the researchers understand the potentially devastating effect on the harsh solar storm, they should be priceless.
