A fireball, or an exceptionally large, bright meteor, was seen streaking across the sky in Finland on Monday night.
Skywarden, an observation system maintained by the Ursa Astronomical Association, momentarily crashed on Tuesday morning after receiving over a hundred reports about the meteor.
The phenomenon could be seen for six seconds (in some cases less than that) at around 8pm in various parts of the country.
The fireball reportedly shone brighter than Venus and flashed yellow, green and white as it disintegrated and went out.
Some observers in Kainuu mistook the glowing streak of light for an aircraft. This led to the rescue department launching an unsuccessful investigation for signs of a plane crash in the Piispäjärvi area.
Members of Ursa's Finnish Fireball Network will be able to calculate the speed, angle and size of the meteor based on images captured by observers.
Jarmo Moilanen, who is part of the team, says that such a bright fireball is a rare occurrence.
"This kind [of phenomenon] can be seen once every ten years. All those who saw it can congratulate themselves,"
Moilanen estimates that the meteor landed across Finland's border with Russia near Lake Ladoga and that any remnant it left behind would weigh a few kilograms.
