The US National Oceanic and Atmospheric Administration publishes space weather forecasts to reduce the impact of space phenomena such as coronal mass ejections and geomagnetic fluctuations due to solar flares (solar storms) on the Earth and artificial satellites. On September 27, 2021, the US National Oceanic and Atmospheric Administration said, 'Aurora borealis in relatively low latitude areas such as New York, Wisconsin, and Washington due to a larger-than-usual solar storm on September 27 and 28. May appear. '

Similarly, the Met Office, which publishes space weather forecasts, has released a forecast stating that 'aurora may appear in northern Scotland on September 28.' The image below shows the 'Aurora may appear at 6 o'clock on September 27, 2021' announced by the Met Office. If you look at the figure, you can see that the predicted location of the aurora has reached the southern part of Canada and is approaching the northern part of the United States.

Furthermore, if you check the figure showing 'Aurora may appear at 21:00 on September 27, 2021', it is predicted that the aurora is likely to appear in the northern part of England where Scotland is located. You can see that.

The US National Oceanic and Atmospheric Administration classifies the scale of solar storms into G1 to G5, and this solar storm is equivalent to the second G2 from the bottom ( shortwave radio communication may be interrupted for tens of minutes). Is predicted.

In addition, small-scale solar storms have only the effect of causing aurora to appear, but large-scale solar storms are known to cause situations such as stopping radio waves for several hours or causing power outages. .. Abdu Jotei, a computer science researcher at the University of California, Irvine , called for action, saying , 'A very large solar storm could render the Internet unusable in large areas.' I am.
