翻译后摘要-本文介绍了两个狮子座流星火球在北方新墨西哥州在1：32和3：06 MST，分别在1998年11月17日晚上的几套测量的协调结果。测量包括两个事件的可见光波段测光，以及Na气辉的过滤后的5890张全天空图像。此外，对于凌晨06点的事件，我们获得了流体动力学产额的次声测量。对于凌晨1点32分的事件，我们获得了一组可见波段电荷耦合器件（CCD）相机拍摄的流星串图像，时间持续到最初撞击后30分钟。测量结果结合起来，得出了强烈的早期闪光的光学效率，以及两颗流星的总爆炸产量和质量。
Abstract— This paper describes the coordinated results of several sets of measurements of two Leonid meteor fireballs over northern New Mexico at 1:32 and 3:06 MST, respectively, on the night of 1998 November 17. The measurements included visible band photometry on both events, as well as filtered 5890 Å all‐sky images of the Na airglow. Also, for the 3:06 a.m. event, we obtained an infrasound measurement of the hydrodynamic yield. For the 1:32 a.m. event, we obtained a set of visible band charge‐coupled device (CCD) camera images of the meteor train for times extending to 30 min after the initial impact. The measurement results have been combined to derive an optical efficiency for the intense early‐time optical flash, and the total explosion yields and masses for both of the meteors.
