Two fireballs during weekend of August 16 and 17, 2025 above South Spain skies.
During the weekend of August 16 and 17, two fireballs were registered with the SMART Project’s detectors operated at Calar Alto (Almería), La Hita (Toledo), Sierra Nevada (Granada), La Sagra (Granada), Otura (Granada), Huelva and Seville observatories.
The first one happened at 23h15 UT of August 16th, while the second one was at 02h54 UT of August 17th.
Several of the cameras located at Calar Alto Observatory, in Almería, also registered these events.
As usual, the PI of the SMART Project, Professor José María Madiedo (Instituto de Astrofísica de Andalucía IAA-CSIC) did the preliminary analysis of both objects. His conclusions are as follows:
August 16th
- Type of event: asteroidal
- Initial speed: 60.000 km/h
- Initial altitude: 96 km
- Final altitude: 68 km
August 17th
- Type of event: cometary
- Initial speed: 239.000 km/h
- Initial altitude: 109 km
- Final altitude: 79 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.
