A huge explosion on the surface of the sun called "solar flare" is expected to occur, and electrically charged particles are expected to reach the earth from the afternoon of the 30th to the 31st.
This effect may affect communication satellites and GPS, and the National Institute of Information and Communications Technology is calling attention.
According to the National Institute of Information and Communications Technology, a huge explosion called "solar flare", which is classified as one of the largest explosions on the surface of the sun, occurred before dawn on the 29th.
This "solar flare" emits a large amount of electrically charged particles such as protons, which are expected to reach the earth from the afternoon of the 30th to the 31st.
For this reason, artificial satellites such as communication satellites, GPS position information, and shortwave wireless communication may be affected for several days after the 30th.
On the other hand, the particles emitted by this "solar flare" do not directly affect people or airplanes around Japan.
In Japan, four years ago, in September 2017, a “solar flare” that was 10 times larger than this time occurred, which had the effect of increasing GPS errors.
The activity of the sun fluctuates in a cycle of about 11 years, and it is now considered to be a time when the activity gradually becomes active.
Takuya Tsugawa, director of the National Institute of Information and Communications Technology, said, "Be careful for a few days as it may affect the use of GPS and some wireless communications."
