Abstract

Ball lightning (BL) has been observed with two slitless spectrographs at a distance of 0.9 km. The BL is generated by a cloud-to-ground lightning strike. It moves horizontally during the luminous duration. The evolution of size, color, and light intensity is reported in detail. The spectral analysis indicates that the radiation from soil elements is present for the entire lifetime of the BL.

球状闪电的光学和光谱特征观测。

用两台无缝隙摄谱仪在0.9公里的距离上观测到了球状闪电。BL是由云对地雷击产生的。它在发光期间水平移动。详细报道了尺寸、颜色和光强的演变。光谱分析表明，土壤元素的辐射在BL的整个生命周期中都存在。
