Abstract

To obtain photographic records of bright fireballs, many stations over a large territory, each with cameras covering the whole sky, are needed. The number of stations operating in Central Europe nowadays hovers around 40, and the average spacing between them is approximately 100 km. The whole system covers an area of about one million sq km. The most developed observational system of the European Network (EN) is in the Czech part, where each station is equipped with one fixed fish-eye camera. The extremely good optical quality of Zeiss Distagon objectives used in these cameras enables us to derive positions from one photograph of the whole sky hemisphere with a precision better than 1 arcmin. The German part is mostly equipped with less precise all-sky mirror cameras. The capabilities of this observational system are demonstrated on two very recent exceptional cases.
