[Explanation] Recently, due to the outbreak of solar flares, aurora appeared in many parts of the northern hemisphere, and the "Carrier Pigeon Flight Index Forecast" issued by the National Space Weather Monitoring and Warning Center also made suggestions such as "cautious release" for "release of doves".
Why does aurora appear on a large scale?
Why are homing pigeons also disturbed?
What impact will the outbreak of solar flares have on our lives?
[Concurrent] Zong Weiguo, researcher of the National Satellite Meteorological Center
To be precise, it (aurora) is not caused by flares, it is also caused by coronal ejecta, that is, if only flares, it will not actually produce aurora, only when the coronal ejecta reaches the earth and triggers a magnetic storm, it will produce aurora.
Magnetic storms will cause the aurora to move from high latitude to low latitude.
[Explanation] The sovereign state stated that the coronal mass ejection caused by solar flares will also affect some biological activities, especially animals that rely on geomagnetic navigation, including homing pigeons.
[Concurrent] Zong Weiguo, researcher of the National Satellite Meteorological Center
There are (and) some indirect effects caused by the sun burst, for example, some biological activities will have a very obvious impact.
Many creatures with geomagnetic navigation are not only homing pigeons. For example, lobsters and turtles have also been studied. Many of them are actually very sensitive to the geomagnetic field, and their homing ability will drop a lot during a magnetic storm.
In May, there was also a (flare). Many homing pigeon users who played with pigeons released them and found that their homing rate dropped sharply.
[Explanation] Will the outbreak of solar flares affect the lives of ordinary people?
The clan state pointed out that it will have an impact on the normal communication of mobile phones and the accuracy of map navigation, but the impact will be short-lived.
[Concurrent] Zong Weiguo, researcher of the National Satellite Meteorological Center
For example, mobile phone communication, the most direct impact is that during the sun's eruption, its radiation will actually increase in various frequency bands. If its radiation frequency band happens to be in the same frequency band as your mobile phone communication, you don’t want to To be disturbed must be disturbed.
On the other hand, it is also possible that the navigation signal will change. Originally, for example, the positioning accuracy could reach the meter level, but now it can only reach the 10 meter level.
There is no good way to shield it, but its impact is generally relatively short.
[Explanation] According to observations, solar active areas have gradually increased in recent years.
The Apostolic State stated that it is expected that the peak year of solar activity may be reached in 2023 or 2024.
