On the nights of November 7th and 8th 2021, two fireball flew above the skies of southern Spain.
Both events were registered with the SMART Project’s detectors operated at Calar Alto (Almería), La Sagra and Sierra Nevada (Granada), La Hita (Toledo) and Seville observatories.
As usual, some of the external surveillance cameras located at Calar Alto Observatory in Almería, also registered this phenomena.
The time of the first one was at 22h52 UT, while the second one took place at 19h13.
The preliminary analysis was carried out by Professor José María Madiedo (Instituto de Astrofísica de Andalucía IAA-CSIC), who is the PI of the SMART Project. The data extracted from the analysis concluded the next:
Fireball of November 7th:
- Event type: Cometary
- Speed: 111.000 km/h
- Initial altitude of the luminous part of the event: 101 km
- Final altitude of the luminous part of the event: 60 km
This fireball happened above the Mediterranean Sea, in front of the Murcia (southeast Spain) coast.
Fireball of November 8th:
- Event type: Cometary
- Speed: 88.000 km/h
- Initial altitude of the luminous part of the event: 87 km
- Final altitude of the luminous part of the event: 45 km
In this case, the entire path happened above the southern part of Andalusia, between Granada and Málaga provinces and close to the coast.
Below are the videos registered with Calar Alto Observatory cameras.

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.
