Ildkulgen blev først set af spanske videnskabsfolk klokken 22:25 lokal tid søndag, mens den passerede de sydlige regioner af Andalusien, Granada go Jaen.
Objektet blev af astrofysiker ved Universidad de Huelva, Jose Maria Madiedo, til avisen El Pais, beskrevet som en del af en asteroide.
Den var af "betragtelig størrelse" så "den kunne overleve sin passage gennem Jordens atmosfære," fortalte Madiedo til Europa Press.

For mere om ildkulger over Spanien se Jose Maria Madiedos' Twitter profil, eller Youtube, eller Universitetets side om ildkugler og meteorer, hvor man kan se at de forskellige ildkugler også har fået en vurdering af deres lysstyrke. Meteoren den 11. december havde fx en størrelsesklasse -14 +-1
Man behøver ikke tage til Spanien for at se ildkugler fx
- Meteor fireball photographed hurtling towards ground in Wraysbury, UK
- Massive meteor fireball explodes several times off the coast of Norway
- Another fireball explodes over Siberian city
- Meteor reported blazing across sky in Denmark
- Meteor fireball 'tore up the skies' in northeast Brazil
Professor Madiedo indicated that the object was detected by a network of high-sensitivity cameras of the University of Huelva, installed at 10 stations in Andalusia and Castilla.
The fireball was also spotted by astronomical stations in the regions of Toledo, Seville, Almeria, Sierra Nevada and Granada.
Witnesses claimed to have heard an explosion associated with the fireball, and to have felt a tremor similar to an earthquake. They've described it as being "brighter than the moon."
Eyewitness accounts and preliminary analysis of the phenomenon led scientists to believe that the "fireball" could have fallen to the ground in the form of a meteorite, Spanish media reported.
Another meteor-like object was caught on cameras last Tuesday, when a large fireball exploded over Siberia. One of the witnesses told RT that it "wasn't as light as day, but still quite bright."
It was seen for three or four seconds and around half a minute later there was a loud bang, triggering car alarms in many parts of the city, the witness said.
The apparent meteor burned up high in the atmosphere as little or no blast sound was heard on the ground by most eyewitnesses, the Emergencies Ministry announced.
