This note emphasizes the importance of very bright fireballs as a powerful source of meteoritic dust in the upper atmosphere and on the Earth’s surface. Recently we obtained a direct observational evidence when we photographed the Šumava Fireball, an object of −22 absolute stellar magnitude, on Dec. 4, 1974 at 17h57.5m UT. This is the brightest object on the European Network photographic records during almost 12 years of systematic fireball observations. We obtained 4. all-sky-camera records of the Šumava Fireball from two Czech and one German station of the Network. The most important combination for the trajectory computations proved to be station No. 5 at Ondrejov (Astronomical Institute of the Czechoslovak Academy of Sciences) and station No. 65 at Bernau (Max-Planck-Institut für Kernphysik, Heidelberg). The results are given in Table 1. At Ondřejov we also obtained 4 spectral records of the Šumava Fireball; the most detailed record has a dispersion of 5 Å/mm.
