A fireball at night, as bright as a full moon - 10.9.2013 at 02.06 Varkaus Observation number 18214

Visibility V / V

Veli-Pekka Hentunen, Warkauden Kassiopeia

Last night 10.9. at 02.06 an exceptionally strong fireball flashed above the Härkämäki observatory. Its brightness was in the order of a full moon. Seen from Härkämäki, the object exploded to the south at an altitude of about 45 degrees in the constellation of Pisces. The target arrived from the direction of the constellation of Perseus and left a tread about 30 degrees long before the explosion. There was still a large cloud of smoke in the sky for about 25 minutes. In the pictures taken by Ursa from Mikkeli, the same fireball can be seen in the north direction, behind Otava! The target has probably been between Varkaus and Mikkeli, because it was visible in Härkämäki to the south and in the constellation of Pisces near the star of gamma Pegasus.

Hienoa, että uudella kameralla alkaa tulla havaintoja tänne Vahtiinkin. :) Komean tulipallon olette napannut.

Todella hurja tapaus! Liki puoli tuntia kestävä savuvana ei ole ihan jokapäiväinen juttu.

Hienosti olette saaneet talteen. Tarkennuksena yllä olevaan kertomukseen, että tämä on siis sama kuin itäkameramme tapaus, ei tämä pohjoisen suunnassa näkyvä tapaus, kuten kertomuksessa mainitaan.

Onpas hieno ilmestys ja näkyypä kamerassa Linnunratakin tosi hyvin.

Ja tässä muuten video ko. tulipallosta. Videolta voi hyvin seurata savuvanan kehitystä.
