García, J. M.; Madiedo Gil, José María
; Castro Tirado, Alberto J.; Jelinek, M.; Trigo Rodríguez, Josep María (2012)
The monitoring of very bright fireball events is one of the aims of the SPanish Meteor Network (SPMN), as these allow us to collect very valuable information on the origin and properties of large meteoroids that can ... -
Analysis of large meteoroids produced by comet 7P/Pons-Winnecke
Rodríguez Ramírez, Antonio; Madiedo Gil, José María; Trigo Rodríguez, Josep María; Konovalova, N. (2012)
Dust ejecta of comet 7P/Pons- Winnecke produces the June Bootid meteoroid stream [1]. This gives rise to an annual display of meteors from about June 22 to July 2, with a maximum activity around June 28. A continuous ... -

Trigo Rodríguez, Josep María; Llorca, Jordi; Weyrauch, Mona; Bischoff, Addi; Moyano Cambero, Carles E.; Keil, Klaus; Laubenstein, Matthias; Pack, Andreas; Madiedo Gil, José María; Alonso Azcárate, Jacinto; Riebe, My; Wieler, Rainer; Ott, Uli; Tapia, Mar; Mestres, Narcís (Meteoritical Society, 2014)
We report and describe an L6 ordinary chondrite fall that occurred in Ardón, León province, Spain (longitude 5.5605°W, latitude 42.4364°N) on July 9th, 1931. The 5.5 g single stone was kept hidden for 83 yr by Rosa Gonzólez ... -
Asteroid 2002NY40 as a source of meteorite-dropping bolides
Trigo Rodríguez, Josep María; Lyytinen, E.; Jones, D. C.; Madiedo Gil, José María; Castro Tirado, Alberto J.; Williams, I. P.; Llorca, Jordi; Vítek, Stanislav; Jelinek, M.; Troughton, Blanca; Gálvez, Francisco (Oxford University Press, 2007)
The existence of asteroidal meteoroid streams capable of producing meteorite-dropping bolides has long being invoked, but evidence is scarce. Recent modelling of previously reported associations suggests that the time-scales ... -
Asteroides y cometas como cuerpos progenitores de meteoritos : su peligro de impacto con la Tierra
Trigo Rodríguez, Josep María; Madiedo Gil, José María (Asociación Española para la Enseñanza de las Ciencias de la Tierra (AEPECT), 2013)
Los asteroides y los cometas son los principales cuerpos que producen meteoritos aunque la Tierra también recibe rocas de diversos cuerpos planetarios como la Luna, Vesta o Marte. Este artículo pretende dar a conocer las ... -
Atmospheric trajectory, orbit and chemical composition of a sporadic bolide imaged in 2011
High-sensitivity CCD video devices are commonly employed to monitor meteor and fireball activity. These systems provide useful data for the determination, for instance, of radiant, orbital and photometric parameters ... -

Madiedo Gil, José María; Trigo Rodríguez, Josep María; Llorca, Jordi; Tancredi, Gonzalo; Edwards, Wayne N.; Rubin, Alan E.; Weber, Patrick (Wiley-Blackwell Publishing, 2010)
The fall of the Berduc meteorite took place on April 7, 2008, at 01 h 02 min 28 s +/- 1 s UTC. A daylight fireball was witnessed by hundreds of people from Argentina and Uruguay, and also recorded by an infrasound array ... -
A bright bolide produced by a meteoroid follwing a Jupiter family comet orbit
One of the techniques employed by the SPanish Meteor Network (SPMN) to monitor the night sky is based on high-sensitivity CCD video de- vices. These have a limiting magnitude of +3/+4 with- out using any image intensifier. ... -
A bright fireball witnessed on august, 17, 2011 over the Iberian Peninsula
The detailed study of bright fireball events is one of the aims of the SPanish Meteor Net- work (SPMN), as these allow us to collect very valu- able information on the origin of the relatively rare meteorite-dropping ... -
Development and continuous spectroscopi campaign in the framework of the Spanish meteor network
Salas, I.; Madiedo Gil, José María; Trigo Rodríguez, Josep María; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Cabrera Caño, Jesús (2013)
One of the aims of the SPanish Meteor Network (SPMN) is the study of the chemical composition of meteoroids from the analysis of the emission spectrum produced when these particles ablate in the atmosphere. Besides, ... -
Emission spectrum and orbital elements of a sporadic fireball imaged in 2011
Marín, D.; Madiedo Gil, José María; Trigo Rodríguez, Josep María; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Pastor, S.; Reyes, J. A. de los (2013)
The characterisation of physical and chemical properties of meteoroids can be performed from the analysis of meteor and fireball events. This provides useful information about the origin and evolution of meteoroid ... -
A fireball produced by a meteoroid belonging to the delta aquilids stream
Nieto, R.; Madiedo Gil, José María; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Trigo Rodríguez, Josep María; Zamorano, J.; Izquierdo Gómez, Jaime; Ocaña Gónzalez, Francisco; Sánchez de Miguel, A.; Pastor, S.; Reyes, J. A. de los (2013)
According to Jenniskens [1], the δ- Aquilids are active from April 10 to April 16, with a maximum peak around April 13. It is currently included in the IAU working list of meteor showers with code 131 DAL. The proposed ... -
A fireball produced by a meteoroid following a retrograde orbit
Álvarez, G.; Madiedo Gil, José María; Trigo Rodríguez, Josep María; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Cabrera Caño, Jesús (2013)
One of the systems employed by the SPanish Meteor Network (SPMN) to perform a continuous monitoring of meteor and fireball activity is based on high-sensitivity CCD video cameras. These devices have been commonly used ... -
The Geminid meteoroid stream as a potential meteorite dropper: a case study
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Castro Tirado, Alberto J.; Ortiz Moreno, José Luis; Cabrera Caño, Jesús (Oxford University Press, 2013)
A Geminid fireball with an absolute magnitude of −13 was observed over the south of Spain on 2009 December 15. This extraordinarily bright event (the brightest Geminid ever recorded by our team) was imaged from two meteor ... -
Historical records of δ-Arietids superfireballs over Spain
Historical reports of bright fireballs are useful to better understand which meteoroid streams can be temptatively associated with meteoritedropping events [1]. We present here a preliminary analysis of a very remarkable ... -
