A large solar explosion erupted last Thursday (28) and is expected to reach Earth on Saturday (30), which could trigger a powerful geomagnetic storm and cause aurora borealis visible in the sky. United State and yes Europe.
The National Oceanic and Atmospheric Administration (NOAA), a US government agency, has issued a “strong” geomagnetic storm warning for today and tomorrow.
The geomagnetic storm scale ranges from G1, or a minor storm, to G5, which is a severe storm. NOAA’s alert is G3.
The National Oceanic and Atmospheric Administration (NOAA) warned in the statement that a geomagnetic storm could cause voltage irregularities and false alarms in some safety and security devices.
This phenomenon can also cause power outages in high-frequency radios and loss of communication on the sunlit side of the Earth.
The most obvious effect of the impending geomagnetic storm is that it will likely overwhelm the aurora borealis, making it visible in large parts of the United States and Europe.
Where can the aurora borealis appear?
Aurora forecasts from the University of Alaska’s Fairbanks Geophysical Institute indicate that, weather permitting, the aurora borealis can be seen from Portland, Oregon, to New York City.
It may also be visible on the southern horizon, such as in Carson City, Nevada, Oklahoma City, and Raleigh, North Carolina.
In Europe, forecasts show, weather permitting, that the aurora borealis could be visible over Norway, Sweden and Finland, and even as far south as Scotland and Saint Petersburg in Russia.
It may also be visible on the southern horizon, such as Dublin, Ireland, and Hamburg, Germany. The Australian aurora, or the so-called “southern lights,” have similar effects.
Projections show that this phenomenon can also be seen on the horizon from Melbourne, Australia, to Christchurch, New Zealand.
