Magnetic storms are unusually active

The statistics show that since the beginning of the year, the magnetic storm has been very unusual.

According to Assoc. Prof. Dr. Ha Duyen Chau, senior expert of the Institute of Geophysics, Vietnam Academy of Science and Technology, if "correct" according to the 11-year operation cycle of the solar storm (magnetic storm), then year 2012 is the time when five storms were active again with the number of 45 - 50 matches and the intensity could reach over 500nT.

However, contrary to the forecast, since the beginning of the year, magnetic storms are still in the "dormant" phase with very little activity and very weak intensity. Statistics show that there have been only 24 matches and very weak intensity only about 150 - 200nT (nT stands for nano magnetic Tesla - unit measuring magnetic storm intensity). For example, on September 3 and September 5, there were 2 consecutive storms from the intensity of less than 200nT. Such intensity does not affect human health (magnetic storms with a intensity of 300nT or more can affect human health).

The explanation for this abnormality is very difficult because the Sun's activity is still beyond human control. The most plausible explanation for this abnormality is that sometimes the 11-year cycle of magnetic storms moves (occurring earlier or later than the 11-year cycle).

Maybe from now until the end of the year, there will be about a few dozen storms from now and the intensity will be stronger, but the intensity is strong to 500 - 600nT, even 1,000nT or not is still in secret. However, the scientific world said that until this time, since the storm still "quiet" , it is likely that the time of the storm from "waking" will have to backward until 2013.

Although unusual storms, however, there is luck in the abnormality, because in some ways it smashes the notions that the Sun's strong activity in 2012 will cause destruction. kill (end of the world). In fact, the Sun's activity has been weak for more than half of 2012.

Moreover, even strong magnetic storms certainly cannot cause the apocalypse because since the Earth was formed so far, there have been millions of storms from happening, many times have occurred But there is no sign that the destructive power of magnetic storms can cause destruction.

Answering the question of 2 storms from September 3 and September 5 related to the flood in Central Vietnam happened at the same time, Assoc. Prof. Dr. Ha Duyen Chau said This is just a coincidence.

In fact, the statistics show that in the years of strong storms, rain, storms and floods are also more active. However, the direct influence, such as the storm from September 3 and September 5 caused the flood in the Central region at that time was impossible.
