AN IM­PRES­SIVE fire­ball which flew over Spain could be ob­served early on Sun­day morn­ing (Novem­ber 4).

The phe­nom­e­non was reg­is­tered with SMART project de­tec­tors at the ob­ser­va­to­ries of Calar Alto in Almería, OSN (Sierra Nevada, Granada), Sevilla, La Hita (Toledo) and La Sa­gra (Granada).

This fire­ball was also recorded with the ex­ter­nal sur­veil­lance we­b­cams at Calar Alto (see photo) in the Sierra de Los Fi­labres, noted the Ger­manS­pan­ish As­tro­nom­i­cal Cen­ter (CAHA) based there.

Fol­low­ing pre­lim­i­nary anal­y­sis by Pro­fes­sor José María Madiedo of the Uni­ver­sity of Huelva and head of of the SMART project, the rock that im­pacted with earth's at­mos­phere came from the Encke comet, which is as­so­ci­ated with the North Tau­rid star shower. The ini­tial speed of the ob­ject was about 100,000km/h, start­ing at an al­ti­tude of around 113 km above the in­land re­gion of Castilla La Man­cha, then mov­ing north-east­ward and fin­ish­ing at an al­ti­tude of 51km above the ground in the same re­gion. Calar Alto (CAHA) fire­ball de­tec­tion sta­tion, to­gether with the one at the Ob­ser­va­tory of Sierra Nevada and oth­ers at dif­fer­ent lo­ca­tions in Spain, are part of the SMART project led by Pro­fes­sor Madiedo to track this kind of ob­ject.
