Bolidensichtung 19.06 Uhr

[Astrofan80]

Vielerorts wurde heute ein sehr heller Bolid mit anschließender minutenlanger Nachleuchtspur gegen 19.06 Uhr in Richtung NO gesichtet. Auf Twitter um in diversen Foren laufen zur Zeit zahlreiche Meldungen ein.

den boliden haben uwe und ich auch gesehen als wir asteroid 2015 tb145 versucht haben aufzufinden .der bolide leuchtete grün und hinterließ eine große abgaswolke.

Herzlichen Glückwunsch zur Sichtung. Im AKM-Forum schreiben sie, dass die Feuerkugel eine Helligkeit von -12 bis -14 mag hatte (Vollmondhelligkeit).

Hier noch ein Link zu einigen Videos von polnischen Dashcams, die den Boliden ebenfalls im Visier hatten: https://t.co/CQuDChVY6C

Am 2. November gabs in Thailand ebenfalls einen mächtigen Boliden.



Man vermutet, dass die Boliden durch den Tauriden-Meteorstrom verursacht wurden.

In diesem Jahr ist die Boliden-Aktivität des Tauriden-Stroms ungewöhnlich hoch. Siehe: http://spaceweather.com/archive.php?view...&year=2015

TAURID FIREBALLS: There no longer any doubt. Earth is passing through a stream of gravelly debris from Comet Encke, source of the annual Taurid meteor shower. Meteoroids the size of pebbles, and larger, are disintegrating as they hit our planet's atmosphere at 30 km/s. To see what effect this is having on the night sky, Martin Popek of Nýdek (Czech republic) activated a low-light camera in his backyard and let it run all night long. This is what it recorded:

There were almost a dozen exploding meteors--all brighter than Venus and one as bright as a crescent Moon. "It was a very active night," says Popek.

Earth runs unto the debris zone of Comet Encke every year around this time. Usually, the encounter produces a minor meteor shower, but 2015 is different.

"This is higher than usual activity," says meteor expert Peter Brown of the University of Western Ontario. "The Canadian Meteor Orbit Radar (CMOR) is seeing stronger Taurid activity than any of the last few years. Our Southern Ontario Meteor Network cameras caught 54 Taurid fireballs from Oct 31 - Nov 4 alone, compared to 22, 18, and 32 Taurids for the entire month of November in 2014, 2013 and 2012 respectively."

These extra fireballs are coming from a "swarm" of gravelly meteoroids that weaves in and out of Comet Encke's dusty debris zone. In some years, Earth hits the swarm; in other years it misses. 2015 appears to be a hit.

"I would say with some confidence the 2015 Taurid 'swarm' is active as predicted by astronomer David Asher," adds Brown. If those predictions continue to be correct, the fireball display could carry on until Nov. 10th. The best time to look, no matter where you live, is during the hours around local midnight when the constellation Taurus is high in the sky. [meteor radar]
