Abstract. A bright fireball appeared on the sky during the spectrophotometric observations with the 2.2-m telescope at the Calar Alto Observatory. The CCD spectrum of the scattered light of the fireball has been recorded. The spectrum is typical for a very bright, slowly moving fireball. For the first time, the spectral region 6600-7150 A could be studied in such a case. Six spectral lines were identified here, the most remarkable being the lithium line at 6708 A. The estimated lithium abundance proved to be consistent with meteoritic values.

Espectros de la galaxia Mrk8 obtenidos consecutivamente durante la noche del 18 al 19 de diciembre de 1988 en el Observatorio de Calar Alto (telescopio de 2.2m). Durante la primera exposición un bólido atravesó el cielo iluminando completamente el interior de la cúpula.
La imagen de la izquierda muestra el espectro del bólido como un exceso del fondo de cielo que es por lo tanto menos intenso en la segunda exposición.
