Fans of the Northern Lights phenomenon were treated to a spectacular show over southern and northern Finland on Sunday, with the Finnish Meteorological Institute (FMI) predicting more of the same for Monday.
The activity is the result of a medium-intensity solar flare (an eruption in the Sun's atmosphere) that occurred on Friday, causing an intense geomagnetic storm.
Residents in central areas of the country were denied a view of Sunday's aurora borealis due to heavy cloud cover, with overcast conditions also forecast for Monday.
"We are expecting clear skies tonight, at least in Lapland and in some places in the south, so the Northern Lights may be visible again in these areas. There will be no auroras in the central parts of the country," FMI meteorologist Heikki Sinisalo confirmed.
According to the FMI, Finland's geomagnetic disturbances are monitored in real time at ISES RWC Finland.
