The editor of the organization's journal, Marko Pekkola, says it was a superbolide, a fireball more than 100 times brighter than a full moon. The fireball was apparently caused by a space rock striking the atmosphere over Northern Ostrobothnia and then exploding over Finland. Ursa says the rock may have weighed some 200 kilogrammes. However it was not clear on Saturday whether any meteorites fell to the ground.
The dazzling 'shooting star' spurred worried telephone calls to emergency centres in various parts of Finnish Lapland, as far apart as Kemi, Enontekiö and Ivalo.
