Two fireballs make the sky shine on August 5th and 11th


Two bright fireballs have been observed from the Calar Alto Observatory in Almería on the nights of August 5 and 11, 2022.

We have no data available for the first one, while for the second one, a beautiful Perseid occurred at 04:08 UT on August 11th. The Perseid crossed the sky of the province of Jaén from the west to the southwest, leaving a beautiful, while short trail in its wake. The SMART Project detectors that recorded the event are those operated at the observatories of Calar Alto in Almería, La Sagra in Granada, El Aljarafe, Seville, Huelva and La Hita in Toledo.

In any case, some of the external surveillance cameras of the Calar Alto Observatory were able to record both objects..

The preliminary analysis carried out by Professor José María Madiedo (Institute of Astrophysics of Andalusia IAA-CSIC), has concluded that it is a commentary event, a meteor detached from comet 109P/Swift-Tuttle that has impacted our atmosphere at an estimated speed of about 224,000 km/h.


The light part of the event has started at an altitude of 114 km above the province of Jaen. The object then moved in a south-westerly direction towards the province of Malaga ending at a final height of 74km.

Below are the videos that have been recorded with the external cameras operated from the Calar Alto Observatory in Almería.

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.
