Researchers from the Finnish Meteorological Institute confirmed that a series of flares from a solar storm began discharging high levels of charged particles into the earth’s atmosphere Wednesday, triggering the colourful displays of light.
Hobbyists have meanwhile reported stunning views in the night sky over Finland in areas as far south as Kirkkonummi, Tampere, Seinäjoki in western Finland and the Savo region in the east.
However the most dazzling displays could be seen in the north, where the borealis lights are usually best detected. Observers in northern Finland were said to have seen exceptionally vivid displays after 10.00 pm Wednesday night.
While stargazers have been gleefully recording the exceptional natural light show caused by the biggest solar storm in five years, experts have expressed concern than the heightened magnetic activity could disrupt satellite signals and radio communications in polar regions. They have also warned that aircraft may be forced to make temporary changes to their polar routes.
The impact of the solar activity is expected to continue into Friday, giving stargazers who missed Wednesday night’s heavenly extravaganza a chance to catch the repeat show Thursday evening.
