Using footage from cameras in different locations, including an ESA-operated camera of the AllSky7 network and cameras in the Southwestern Europe Meteor Network (SWEMN), a recent fireball’s trajectory was calculated by SWEMN and its origins traced back in time. Entering the atmosphere at a height of 100 kilometres over Madrid and burning up at 77 kilometres above the Spanish province of Guadalajara, the icy body is thought to have been about 10 cm in size before contact with Earth and to have originated from an icy comet, once thought to be an asteroid.
