      Lunar impact flashes from geminids: Analysis of luminous efficiencies and the flux of large meteoroids on earth  [Article]

      Ortiz, J. L.; Madiedo Gil, José María; Morales, Nicolás; Santos-Sanz, P.; Aceituno, Francisco J. (Oxford University Press, 2015)
      We analyse lunar impact flashes recorded by our team during runs in December 2007, 2011, 2013 and 2014. In total, 12 impact flashes with magnitudes ranging between 7.1 and 9.3 in V band were identified. From these, nine ...

      Near-earth object 2012XJ112 as a source of bright bolides of achondritic nature  [Article]

      Madiedo Gil, José María; Trigo-Rodríguez, Josep Maria; Williams, Iwan P.; Konovalova, Natalia A.; Ortiz, J. L.; Castro-Tirado, A. J.; Pastor, Sensi; De Los Reyes, José A.; Cabrera Caño, Jesús María (Blackwell Publishing Ltd, 2014)
      We analyse the likely link between the recently discovered near-Earth object 2012XJ112 and a bright fireball observed over the south of Spain on 2012 December 27. The bolide, with an absolute magnitude of -9 ± 1, was ...

      Spectroscopy and orbital analysis of bright bolides observed over the Iberian Peninsula from 2010 to 2012  [Article]

      Madiedo Gil, José María; Trigo-Rodríguez, Josep Maria; Ortiz, J. L.; Castro-Tirado, A. J.; Pastor, Sensi; De Los Reyes, José A.; Cabrera Caño, Jesús María (Oxford University Press, 2013)
      We present the analysis of the atmospheric trajectory and orbital data of four bright bolides observed over Spain, one of which is a potential meteorite dropping event. Their absolute magnitude ranges from -10 to -11. Two ...

      The 2011 October Draconids outburst-I. Orbital elements, meteoroid fluxes and 21P/Giacobini-Zinner delivered mass to Earth  [Article]

      Trigo-Rodríguez, Josep Maria; Madiedo Gil, José María; Williams, Iwan P.; Dergham, Joan; Cortés, Jordi; Castro-Tirado, A. J.; Ortiz, J. L.; Zamorano G., Jaime; Ocaña, Francisco; Izquierdo, Jaime (Oxford University Press, 2013)
      On 2011 October 8, the Earth crossed the dust trails left by comet 21P/Giacobini-Zinner during its 19th and 20th century perihelion approaches with the comet being close to perihelion. The geometric circumstances of that ...

      The 2011 October Draconids outburst-II. Meteoroid chemical abundances from fireball spectroscopy  [Article]

      Madiedo Gil, José María; Trigo-Rodríguez, Josep Maria; Konovalova, Natalia A.; Williams, Iwan P.; Castro-Tirado, A. J.; Ortiz, J. L.; Cabrera Caño, Jesús María (Oxford University Press, 2013)
      On 2011 October 8, the Earth crossed dust trails ejected from comet 21P/Giacobini-Zinner in the late 19th and early 20th Century. This gave rise to an outburst in the activity of the October Draconid meteor shower, and an ...
