On the night of September 21, at 20:27:59 UT, a bright fireball crossed the skies over the Porto region in Portugal. This event was recorded from the observatories of Calar Alto (Almería), Sierra Nevada, La Sagra (Granada), La Hita (Toledo), Seville, and La Coruña. 
What is most remarkable is that the phenomenon was captured by the cameras of the Calar Alto Observatory, located in Almería, about 600 kilometers away in a straight line. This demonstrates the capability of the SMART Project detectors, which can register fireballs not only over Andalusia, but across practically the entire sky of the Iberian Peninsula.
The preliminary analysis of this event is being carried out by Professor José María Madiedo (Institute of Astrophysics of Andalusia, IAA-CSIC), Principal Investigator of the SMART Project, and will determine parameters such as:
- Tipo de evento: asteroidal
- Velocidad inicial: 73,000 km/h
- Altitud inicial: 87 km
- Altitud final: 40 km
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 (IAA) to track that kind of objects. Specifically, Calar Alto (CAHA) station and the one at Sierra Nevada (IAA-CSIC) constitute a collaboration agreement between the IAA researcher José María Madiedo and both institutions.
