The term “Aurora Borealis” refers to a group of light phenomena that occur in the high atmosphere at altitudes of around 100 km. It is one of the major space weather phenomena. It is common and more visible in the polar regions ( aurora australis, aurora borealis).
An aurora borealis or the Northern Lights may be visible in the sky on Saturday night, from central Europe, according to the National Oceanic and Atmospheric Administration (NOAA). People will be able to see it after dark. A large solar flare that erupted on October 28 will reach the Earth tonight and could result in a strong geomagnetic storm. This will give the Czech people a chance to observe the astonishing phenomenon in the night sky.
“On the night from Saturday to Sunday, there will be a high chance of observing auroras from central Europe, including the Czech Republic and Slovakia,” says Petr Horálek from the Silesian University in Opava, referring to information from the US National Oceanic and Atmospheric Administration.
“If the geomagnetic storm is as strong as astronomers predict, the phenomenon will most likely be observable from our area after dark. According to local astronomers, the best chance to observe it will be during the first half of the night in areas with low light conditions. “The weather forecast is very good so far, and the moon won’t rise until the second half of the night and therefore will not interfere with its light,” Horálek explains.”To observe it, you need to find a place with a clear view to the north, without light pollution,” he added.
The last significant aurora was seen in the Czech Republic in 2015. The National Oceanic and Atmospheric Administration issues ratings from G1 (minor) to G5 (extreme) for potential geomagnetic storms. Tonight’s potential storm rates a G3 (strong) on their scale. Along with the visible aurora, the geomagnetic storm can also cause electrical problems, radio blackouts, and other effects.
