Norwegians have been left awestruck by what experts say was an unusually large meteor that illuminated the night sky in the country's south-east.
Footage shows powerful flashes of light over Norway, followed by what witnesses described as loud bangs on Sunday.
Norwegian police say they received a flurry of emergency calls but there were no reports of injuries or damage.
A team of experts are hunting for the meteor, which they believe landed in a forest near the capital, Oslo.
A meteor is a space rock that has burned up after entering Earth's atmosphere at high speed.
The Norwegian Meteor Network says Sunday's fireball was visible for at least five seconds after it appeared at about 01:00 local time (23:00 GMT).
