Solar storms or geomagnetic storms are disturbances in the Earth’s magnetosphere caused by coronal mass ejections (CME) or coronal ejections and solar wind.
Citing Earth.com, NOAA issued a severe geomagnetic storm warning on September 12 and will continue until September 14, 2024. However, since September 16 things have calmed down, with only a few solar flares reported .
However, the solar storm that happened still affected the earth. Especially regarding the presence of the northern lights.
Because the blowing solar wind carries charged particles from the sun that interact with gases in the earth’s atmosphere. As a result, the color of the light goes around the North and South Poles.
Normally, the northern lights can only be seen from areas within the aurora oval region which includes the Arctic regions of Scandinavia, Russia, Alaska and Canada. But this year, the light can be seen in the lower 48 states far from the aurora oval.
So in May 2024, people will be observing the northern lights in Oklahoma and Florida. In November, the northern lights or what is known as the aurora borealis can be seen further south in the Netherlands.
About Solar Storm
The surface of the Sun is a moving environment. The brightest star in the Milky Way galaxy moves through an 11-year solar cycle.
When this cycle occurs, a burst of radiation occurs in the form of a CME or solar flare that burns out from the core of the star. Solar flares are of high frequency, high intensity, travel through space, and interact with the Earth’s magnetosphere.
This interaction not only creates the aurora borealis phenomenon, but also causes power and radio blackouts. NOAA’s Space Weather Prediction Center issued a warning.
According to them, solar storms can cause voltage anomalies, interfere with Earth’s orbital satellites, and disrupt satellite navigation systems. However, if you want to hunt for the aurora borealis, this group provides notes.
Because basically the aurora will be visible with a forecast of 30 minutes. This can happen if the weather is possible at night.
The strongest geomagnetic storm ever recorded was in September 1859. At that time, the sun released G5 explosions and produced the northern lights visible from Mexico to Hawaii .
According to legend, this light was so bright that miners in Colorado thought it was the sunrise. In addition, New Englanders say they can read after dark because the light is so bright.
Effects of solar storms in Indonesia
Widely discussed, the Acting Head of the Center for Technical Seismology, Geophysics and Time Signals at the Meteorology, Climatology and Geophysics Group (BMKG) Setyoajie Prayoedhie explained that Indonesia was not affected by anything.
“This can happen because the Indonesian region is on the equator so it will be protected by a strong magnetospheric belt,” he said, quoted from the detikEdu archives.
In addition, BMKG also found that the level of disturbances due to magnetic storms detected in Indonesia was low. This phenomenon will have a greater impact on countries located in the northern and southern hemispheres.
