Ursa received numerous sightings of the fireball from various parts of southern and central Finland after 8:18pm on Tuesday.
The trajectory of the fireball is still being investigated. A mathematician of Ursa's fireball research group, Esko Lyytinen, gives a preliminary estimate that the phenomenon appeared over Narva in Estonia at the height of about 95km and vanished from sight around Heinola in southern Finland at the height of about 45-50km.
“We’ve had very good luck as the skies happened to clear at exactly the right moment and our automatic cameras recorded such a wonderful fireball. Otherwise, the whole night in Mikkeli was mostly cloudy,” says Aki Taavitsainen, head of Ursa’s Mikkeli office.
