A new study showed that shiny plasma rings on the surface of the sun “flashing” hours before they unleashed dangerous solar torches. The researchers say new results can help create more reliable weather forecasts in space.
Solar torches are a violent vessel of electromagnetic radiation that is released from the sun when the invisible magnetic field lines are diverted on the surface of the sun until they are finally captured. These most common explosions occur around solar spots – dark spots where the magnetic field lines flow through the surface of our home star – often pull the plasma from the surface of the sun to sparkling horse forms, known as coronary rings, before they are blowing on her head.
These stellar explosions can send waves of radiation to Earth Operation of temporary power outages. Blaces can also release rapid clouds of magnetic plasma, known as Coronary mass ejaculation (CMES), which sometimes covers our planet and causes The most powerful magnetic storm for 21 yearsThat was drawn Auroras is widespread around the world.
In the new study, published on December 6, 2024 in Astronomical Physics Magazine messages And January 15th at the 245 meeting of the American Astronomical Society in Maryland, the researchers analyzed multi -length images of the coronary rings that preceded 50 solar torches, filmed by NassaSolar Energy Dynamics Observatory (SDO). This revealed that the episodes emitted from small flashes from Invisible UV light In specific wavelengths shortly before unleashing.
“The results are really important to understanding torches and may improve our ability to predict dangerous weather in space,” a participant in the study Emily MassonA researcher at Science Inc. said. In San Diego, in a statement.

The researchers pointed out that this palpitational can “indicate torches coming for two hours to six hours with the passage of 6 to 80 percent,” a significant improvement in the current methods. They added that the severity of the palpitations is also linked to the power of the torches received.
“However, the [study] “There is a need for more notes to confirm this link,” NASA representatives say in the statement.
Currently, the sun spit from solar energy flares, as there is not tomorrow, thanks to the continuous The maximum solar energy The peak in the activity cycle of approximately 11 years-so there will be no data shortage for follow-up studies.
Space weather forecasting
Solar activity is very difficult, and scientists can still make mistakes in predictions. For example, continuous The maximum solar energy reached early and was more active From the scholars expected at first.
Unscianity can cause these issues when sudden solar storms start. For example, satellite operators have lost several spacecraft in recent months after they were It came out of the low -Earth orbit By unexpected fluctuations in Atmosphere Because of the solar storms.
