Analisys of a superbolide observed over the Iberian Peninsula on July 21, 2012
A superbolide was observed on July 21, 2012 over the center and south of Spain. The event was recorded in the framework of our continuous fireball monitoring and spectroscopic campaigns. Besides, because of optimal ...
Analisys of a sporadic fireball recorded over Spain in 2012
The SPanish Meteor Network (SPMN) is currently performing a continuous monitoring of meteor and fireball activity by means of 25 observing stations located in Spain. The analysis of events simultaneously imaged from, ...
Analisys of a superbolide from a domocloid observed over Spain on 2012 July 13
(Oxford University Press, 2013)
A superbolide with an estimated absolute magnitude of−20±1was seen on 2012 July 13 over the centre and south of Spain. This extraordinary event, which was witnessed by numerous casual observers, was recorded in the ...
Orbit, emission spectrum, and photometric analysis of two flickering sporadic fireballs
(EDP Sciences, 2013)
We present the observations of two fireballs that exhibit fast and quasi-periodic brightness variations along their atmospheric path. This phenomenon, which is known as “flickering”, is associated to the entry of spinning ...
Linking a fireball to its likely parent near earth object by means of orbital analysis software tools
The identification of their progenitor bodies is crucial to increase our knowledge on the origin and evolution of meteoroid streams. Traditionally, the similarity between two orbits has been used to link a given meteoroid ...
On the chemical nature and orbit of meteoroids from the omicron draconid stream
The omicron Draconids were first observed by Denning in the 19th Century . The activity was, however, modest, with a zenithal hourly rate (ZHR) of about 10–12. Denning  also reported observations in 1929 but in ...
