论文摘要
提出了一个由824个火球(明亮的流星)组成的目录,该目录由2017 - 2018年的中欧的全天空数字摄影摄像机网络观察到。描述了1963年成立的欧洲火球网络的地位。相机收集流星的数字图像比大约-2的绝对幅度和辐射光曲线更明亮,其时间分辨率高于幅度〜 -4。无论其进入速度如何,都检测到所有大于5克,对应于约2 cm的量化的灭气体。检测到高速酿酒素的质量约为0.1克。在2017 - 2018年期间,观察到的麦体观测到的子流线最大,质量约为100 kg,大小约为40厘米。解释了数据分析的方法,并详细描述了所有目录条目。提供的数据包括火球日期和时间,大气轨迹和速度,各种坐标系统中的辐射,地层中心轨道元素,最大亮度,辐射能量,辐射能量,初始和末端质量,最大遇到的动态压力,物理分类以及可能的淋浴成员资格。有关火球频谱的基本信息可用于一些明亮的火球(显然<-7)。提供了整个样本的简单统计评估。科学分析在随附的论文中提出。
A catalog of 824 fireballs (bright meteors), observed by a dedicated network of all-sky digital photographic cameras in central Europe in the years 2017-2018 is presented. The status of the European Fireball Network, established in 1963, is described. The cameras collect digital images of meteors brighter than an absolute magnitude of about -2 and radiometric light curves with a high temporal resolution of those brighter than a magnitude ~ -4. All meteoroids larger than 5 grams, corresponding to sizes of about 2 cm, are detected regardless of their entry velocity. High-velocity meteoroids are detected down to masses of about 0.1 gram. The largest observed meteoroid in the reported period 2017-2018 had a mass of about 100 kg and a size of about 40 cm. The methods of data analysis are explained and all catalog entries are described in detail. The provided data include the 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 the fireball spectrum is available for some bright fireballs (apparent magnitude < -7). A simple statistical evaluation of the whole sample is provided. The scientific analysis is presented in an accompanying paper.
