The magnetic storm that began on August 12 has ended. This is reported on the website of the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences and the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences.
Currently, the geomagnetic index Kp is at the level of 2-3, which corresponds to a calm state of the Earth's magnetic field.
The risks of new flares and emissions on the Sun will persist for several more days. Astronomers consider the resumption of a magnetic storm unlikely, however, high risks of solar activity affecting the Earth will remain for at least two to three days.
On the night of August 12, in several Russian regions, including Moscow and St. Petersburg, it was possible to observe the Northern Lights associated with a strong magnetic storm of level G4.
New Flare Forecasting Methodology
Russian specialists from the Crimean Astrophysical Observatory (CrAO) have developed a methodology for early forecasting of solar flares accompanied by coronal mass ejections. These flares can cause magnetic storms on Earth, which affect weather-sensitive people, as well as microelectronics, navigation systems, and electrical equipment.
The methodology is based on identifying precursors in the chaotic flow of solar radiation. Specialists have discovered special sequences at various frequencies of electromagnetic waves that appear before flares. Data from spacecraft constantly observing the Sun were analyzed to develop the method.
Deputy Director for Scientific Work of CrAO, Alexander Volvach, said that the events of ordering chaos, discovered in the data, precede flares by several days. With the accumulation of information and refinement of the parameters of the precursors, a system will be created that will allow predicting flares 1–2 weeks before their occurrence.
The implementation of the methodology will require infrastructure for continuous monitoring of the Sun, including satellites in a sun-synchronous orbit or a network of ground-based observatories for round-the-clock monitoring. A patent has already been obtained for the invention.
Earlier, www1.ru reported that the Earth was covered by a magnetic storm. It was expected to last until the end of Monday.
