The spectrum of fireball light taken with a 2-m telescope

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 Å could be studied in such a case. Six spectral lines were identified here, the most remarkable being the lithium line at 6708 Å. The estimated lithium abundance proved to be consistent with meteoritic values.
