The new year began with a spectacular display of the Northern Lights in many parts of Finland.
The Aurora show was especially vibrant and visible in western and northern Finland on Wednesday night.
According to the Finnish Meteorological Institute (FMI), a coronal mass ejection (CME) reached Earth on New Year's Eve, with its effects still visible the following night. The chances of seeing the Northern Lights will decrease as the week continues.
A coronal mass ejection (CME) is a large release of solar plasma from the Sun, often accompanied by solar flares that emit X-rays. The corona is the Sun's outermost layer of hot plasma. When a CME reaches Earth, it interacts with the planet’s magnetic field, causing the aurora borealis.
