Fireball in December 4th 2015


During the night of December 4th 2015, a bright fireball could be observed at 22h09m UT. The object could be seen from south Spain. This event was observed and registered at Calar Alto Observatory, and also with the fireball detection station operated at La Sagra (Granada), La Hita (Toledo) and Sevilla Observatories.

The phenomena has been analyzed by Professor Madiedo (University of Huelva). Following his analysis, the fireball started at an altitude of about 96 km above Mediterranean Sea, then moving towards the Strait of Gibraltar with southwestward direction, finishing when the fireball had an altitude of 33 km.

In the image above you can see the object's path over the sea. And below, the video recorded with Calar Alto Observatory south surveillance camera.


Calar Alto (CAHA) fireball detection station, together with the one at the Observatory of Sierra Nevada (IAA-CSIC) and others placed at different locations in Spain, are part of the S.M.A.R.T. project led by Professor José María Madiedo (University of Huelva) to track that kind of objects. Specifically, Calar Alto (CAHA) station and the one at Sierra Nevada (IAA-CSIC) constitute a collaboration agreement between Professor Madiedo and both institutions.
