Fireball 2011.05.21_21.48.12 ± 1 U.T.

Bolide fra la Germania e l'Austria, nella stessa direzione e distanza ( circa ) degli sprite ripresi il 19 Maggio dalla stessa stazione video Ferrara TLE Tracker, direzione nord ( azimut 357 )

Fireball 2011.05.21_21.48.12 ± 1 U.T.

Traccia completa (J2000)

AR i: 9.921
Decl i: 51.990

AR f: 20.879
Decl f: 45.963

Durata transito: 3.88
Durata scia: 0.00
Nessuna frammentazione
Nessun flare

Magnitudine apparente max: -4 ± 0.5

Magnitudine Zenitale: -9 ± 0.1

Sciame meteorico: SPO

Note: altezza iniziale 9° altezza finale 2°

Spettro al primo ordine: NO

Ripresa a colori: NO






simulazione di proiezione al suolo se il punto iniziale è ipotizzato a 80 km e il punto finale a 60 km di quota:

Notevole, considerando la bassa altezza sull'orizzonte dovrebbe essere stato un bel bolide.

Ripresa dall'Austria. Foto di Hermann Koberger (C) Copyright 2011, veramente bella!

Uauh che spettacolo!!!!

aggiunti dati e simulazione...

Notare come anche dalla ripresa dell'Austria il bolide appaia a Nord, quindi la proiezione simulata con l'oggetto sopra alla Germania pare realistica.

Here is picture of this fireball, video was recorded at Modra station (Central Europe Meteor Network), data-set will be add as soon as possible (csv file from Ufo Analyzer)...

Thank you Jakub and welcome.

Welcome Jakub,

just the look you are ready, yuo send we, your . csv file and. xml for triangular.

Very Thanks

Bye

Comments:
Tisserand invariant T= 3,101 (maybe asteroid, maybe cometary source)
No agreement with orbits of periodical comets, or non periodical, or asteroids
10 agreements with orbits in Lindblad photo catalog
Agreement is if Dsh criterion is under 0,2...

Thank You Jakub, very good.

Good results Jakub, from international collaboration

Your result from video Modra Station?

Clear Sky

I´m sorry for a little chaos:-) AGO is the same station as Modra, because AGO means "Astronomical and geophysical observatory" and Modra is the name of village. Another stations in CEMENT network don´t have this fireball, because we have lower edge of FOV approximately 10-15 degrees above horizon. AGO Modra have all sky camera. I see through data-sets from HMN (Hungary network), but in Hungary were in 21.5.2011 bad weather conditions.

So my data-set from AGO Modra will be only one in our network probably:-(
