Three fireballs on the night from July 25th to 26th


Three fireballs have been registered during the last hours of July 25th and first hours of July 26th. Above picture shows the three fireballs.

First fireball happened at 20h42 UT (22h42 local time) of July 25th. Second one took place at 23h04 UT (01h42 local time, already on July 26th). And the last one, was registered at 01h18 UT (03h18 local time).

And also, they were observed as well from several of the external cameras located at Calar Alto Observatory in Almería.

At present, we still have no data concerning the first fireball (the one at 20h42 UT).

Professor José María Madiedo (Instituto de Astrofísica de Andalucía IAA-CSIC), SMART Project PI, has carried out the preliminary analysis of the second and third fireballs.

Concerning the second fireball, this object had an asteroidal origin.

Its initial speed was of 57.000 km/h. The luminous part of the event started at an altitude of 104 km above Jaen province. Then the object moved southeastward and entered into Granada province where it finished at an altitude of 26 km. The above image shows the path this object followed above Jaén and Granada provinces.

Regarding the last fireball of the night, the one at 01h18 UT, and path 26 1which its preliminary analysis was also done by Professor José María Madiedo, its origin was cometary, with a speed of 91.000 km/h. It happened between Córdoba and Jaén provinces (South Spain), with initial altitude of 99 km above Córdoba province and final altitude of 76 km above Jaén province.

The right image shows its path above the ground in Southern Spain.

Below are all the videos that could be registerd of the three fireballs with the Calar Alto Observatory external 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.
