An inexplicable magnetic storm collapsed to the ground

On the night of September 10, a tangible magnetic storm suddenly occurred on Earth. Scientists registered it, but called “completely incomprehensible and difficult to explain”, so it was not predicted and Experts cannot understand what exactly provoked her.

“The event was absent in forecasts. But the riddle is not even this, but the fact that even retroactively it is completely impossible to understand what happened on Earth or near it, which could cause such a violent reaction of the magnetic field, ”they said in Laboratory of solar astronomy of Iki and HSFZ.

Scientists say that the main cause of magnetic storms are external blows from the sun (the arrival of plasma clouds or flows of quick sun wind from coronal holes), but the graphs of the solar wind show that nothing came to the ground on the environment at night at the beginning of the day to see anything that could be identified with the cause of such a sharp event (and the geomagnetic index of noble For a long time, and increased with a jump as if with a sudden blow). Other graphs (density, temperature) do not give clocks, received over the past day. By comparing the time, it would be possible to assume that part of a rather large pro -Buberan reached the planet, thrown out of the sun about 4 days ago And he who flew, as it was believed, greatly past the earth. Could the plasma with some complex ways, having drove along the solar system, nevertheless partially hook the earth? The hypothesis would be good if everything was not the same problem that nothing came to the ground at all. ”

The only explanation of what happened, at least somehow fitting into the framework of science, call the formation of an unusually large Subburi – Phenomena in which the energy of the magnetosphere is released without obvious external causes. “We are, as a rule, a spontaneous violation of equilibrium in the tail of the earth's magnetosphere (an extended structure that stretches in a length of more than 100 thousand kilometers in the anti-salt direction). This phenomenon was first described as a sudden formation of spontaneous polar radiance, which were indeed observed at night. So or not, it will be possible to understand only by the results of a detailed study. But so far this is the only explanation that allows you to reconcile with what happened, ”said laboratories of solar astronomy of Iki and HSFZ, noting that This year is the first case of such a large event. Although perhaps Some of them could be missed against the background of the high activity of the sun, which allowed them to attribute them to one or another external influences.
