Last April 23rd 2021, at 04h03 UT, a nice Lyrid flew above Mediterranean Sea, just in front of Murcia Region coasts.
This object could be registered with the SMART Project’s detectors operated at Calar Alto (Almería), Sierra Nevada (Granada), La Sagra (Granada), La Hita (Toledo) and Seville observatories.
Calar Alto Observatory northeast external surveillance webcam could also follow this event.
As states the preliminary analysis carried out by Professor José María Madiedo (Instituto de Astrofísica de Andalucía IAA-CSIC), and SMART project's PI, this event was caused by a rock detached from a comet which impacted against our atmosphere at an estimated speed of 165.000 km/h.
The luminous part of the phenomena started at an altitude of 114 km above Mediterranean Sea. Then the object moved westward towards Murcia coast, and finished at an altitude of 60 km above the sea.
The image on the left shows the stacked fireball frames, the center one shows a single frame and the right map is the path this object followed above Mediterranean Sea.
Below are the videos recorded at Calar Alto Observatory. The first one is the one of the surveillance webcam, and the second one is the SMART Project detector's.
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.
