On 10 June 2012, an Earth-grazer meteor which lasted over 17 s with an absolute magnitude of -4.0 $\pm$ 0.5 was observed over Spain. This work focuses on the analysis of this rare event which is, to our knowledge, the faintest Earth-grazing meteor reported in the scientific literature, but also the first one belonging to a meteor shower. Thus, the orbital parameters show that the parent meteoroid belonged to the Daytime $\zeta$-Perseid meteoroid stream. According to our calculations, the meteor…

Where Did They Come From, Where Did They Go: Grazing Fireballs
For centuries extremely long grazing fireball displays have fascinated observers and inspired people to ponder about their origins. The Desert Fireball Network is the largest single fireball network
Meteors with extreme beginning heights from observations with high-sensitivity super-isocon TV systems
Meteors with extremely high altitudes are considered. Parameters of seven meteors having anomalous beginning heights recorded with highly sensitive super-Isocon TV systems are presented. One 1993
3D meteoroid trajectories
Abstract Meteoroid modelling of fireball data typically uses a one dimensional model along a straight line triangulated trajectory. The assumption of a straight line trajectory has been considered an


The impact and recovery of asteroid 2008 TC3
A dedicated search along the approach trajectory recovered 47 meteorites, fragments of a single body named Almahata Sitta, with a total mass of 3.95 kg, identifying the asteroid as F class, now firmly linked to dark carbon-rich anomalous ureilites, a material so fragile it was not previously represented in meteorite collections.
The Northern χ-Orionid meteoroid stream and possible association with the potentially hazardous asteroid 2008XM1
We present new orbital data and dynamic results pointing towards the origin of the Northern χ -Orionid meteoroid stream, which is a part of the Taurid meteoroid complex. A new software package was
On the activity of the γ-Ursae Minorids meteoroid stream in 2010 and 2011
Accurate orbital data obtained for the recently discovered γ -Ursae Minorids meteoroid stream during the 2010 and 2011 Spanish Meteor Network and Finnish Fireball Network observing campaigns are
Interaction of large Taurid meteoroids with the Earth's atmosphere
Results of the detailed analysis of the luminosity and ablation of bright Taurid, that break up into individual pieces in the Earth's atmosphere due to the aerodynamic pressure are presented. The aim
The outburst of the κ Cygnids in 2007: clues about the catastrophic break up of a comet to produce an Earth-crossing meteoroid stream
Using high-resolution, low-scan-rate, all-sky CCD cameras and high-level CCD video cameras, the SPanish Meteor and fireball Network (SPMN) recorded the 2007 κ Cygnid fireball outburst from several
Fireball end heights: A diagnostic for the structure of meteoric material
An earlier analysis of Prairie Network fireball trajectory data by the authors failed to discriminate between the varieties of meteoric materials that are thought to be present. The Lost City
The strength of cometary meteoroids: clues to the structure and evolution of comets
Meteoroid behaviour during atmospheric interaction provides clues about the strength and density of cometary disintegration products, establishing a bridge between different research fields. We have
Fall, recovery, and characterization of the Novato L6 chondrite breccia
The Novato L6 chondrite fragmental breccia fell in California on 17 October 2012, and was recovered after the Cameras for Allsky Meteor Surveillance (CAMS) project determined the meteor's trajectory
Numerical integrations are performed on test-particle orbits similar to those of 2PlEncke and (6063) Jason. For purely gravitational integrations, or integrations with non-gravitational forces
Multi-station Video Orbits of Minor Meteor Showers
During 2006 the SPanish Meteor Network (SPMN) set up three automated video stations in Andalusia for increasing the atmospheric coverage of the already existing low-scan-rate all-sky CCD systems.
