The National Oceanic and Atmospheric Administration (NOAA) announces that the expected geomagnetic storm could cause auroras visible from Monday evening, September 16, 2024. If conditions continue, more southern regions will be able to observe this natural spectacle.
With a bit of luck, the Northern Lights will be visible tonight in France
The Sun is currently going through a phase of high activity, corresponding to its 11-year cycle. Many spots have been observed on the Sun in recent months. But it is one spot in particular, which astronomers have given the name “AR3825”, which is responsible for this solar flare.
These spots, indicators of the intensity of solar activity, produce eruptions which project charged particles towards the Earth. These particles interact with the Earth’s magnetic field, creating light phenomena such as the northern lights. Although less powerful than the storm of May 2023, this storm could nevertheless generate auroras visible in France, if atmospheric conditions allow.
If it’s a nice day where you are on Monday night, take a look at the sky.
Part of a recent solar flare that occurred earlier this weekend will reach Earth’s vicinity and could cause a significant geomagnetic storm, with the possibility of intense auroras.— Astropierre (@astropierre) September 15, 2024
Solar flare: no danger to the public but spectacle visible only in the countryside
Geomagnetic storms are classified on a scale from G1 to G5, with G5 being the most extreme. The expected G3 storm could theoretically intensify to a G4 level, making auroras visible farther south. In May 2024, a G5 storm produced auroras visible as far south as Florida, an exceptional event. According to the National Oceanic and Atmospheric Administration (NOAA), the storm expected on September 16, 2024 could be visible in several countries, especially those located in Europe and North America.down to latitudes as low as California and Missouri.
September, with its equinox effect, is a good month for auroras, as magnetic disturbances tend to be more intense. To observe these auroras, it is advisable to stay away from cities to avoid light pollution. Although the storm could pose risks to satellites and electrical infrastructure, scientists do not anticipate any immediate danger to the public.
