Leonids 1995: Taurid Fireball

November 17, 1995 at 23h59m33s UT (Andalucia, Spain)





Introducing the Great Taurid Fireball

[fireball] On november 17, 1995 at 23h59m33s UT a magnificent -10 Taurid fireball exploded above the Province of Andalucia of Spain. This photo is taken by the DMS observing team at Alcudia.

The fireball appeared during the Leonid observing campaign which was setup by the Dutch Meteor Society in collaboration with SOMYCE; the Spanish Meteor Society. Sonic booms of this Taurid fireball have been recorded at Zafaraya and Almedinilla with video-camera's. The fireball has been photographed by three stations of the network and is the brightest fireball ever photographed by members of DMS.

Most probable Voo : 32.901 +- 0.008 km/s

Remarks:

All values of Voo in second column are computed by means of the interpalation formula described in Jacchia and Whipple (Smithson. Contr. Astrophys. 4, 97-129, 1961)

All values of Voo in thirs column are computed by means of the no-fragmentation model described in Ceplecha et al. (A&A 279, 615-626, 1993).

Delta H is the range of heights from which Voo is computed
