824 fireballs observed in 2017-2018

DOI

A catalog of 824 fireballs, i.e. bright meteors, observed by a dedicated network of all-sky digital photographic cameras in central Europe is presented. The current status of the European Fireball Network, established in 1963, is described. The cameras collect digital images of meteors brighter than absolute magnitude about -2 and radiometric light curves with high temporal resolution of those brighter than magnitude ~-4. All meteoroids larger than 5grams, corresponding to sizes of about 2 cm, are detected regardless of their entry velocity. High-velocity meteoroids are detected down to masses of about 0.1gram. The largest observed meteoroid in the reported period 2017-2018 had a mass of about 100kg and size of about 40cm. The methods of data analysis are explained and all catalog entries are described in detail. The provided data include fireball date and time, atmospheric trajectory and velocity, the radiant in various coordinate systems, heliocentric orbital elements, maximum brightness, radiated energy, initial and terminal masses, maximum encountered dynamic pressure, physical classification, and possible shower membership. Basic information on fireball spectrum is available for some bright fireballs. A simple statistical evaluation of the whole sample is provided. The scientific analysis is presented in an accompanying paper.
