We analyze the activity of the Northern ω-Scorpiid meteor shower between 2010 and 2012. For this purpose we have employed an array of low-lux CCD video cameras and spectrographs deployed at different astronomical observatories in Spain. As a result of our survey, the atmospheric trajectory and radiant position of 11 of these meteor events were obtained. The tensile strength and orbital parameters of the progenitor meteoroids have been also calculated. The calculated orbital data and the behaviour of these meteoroids in the atmosphere are compatible with an asteroidal origin of this stream. In addition, we discuss a unique emission spectrum recorded for one of these meteors. This is, to our knowledge, the first North ω-Scorpiid spectrum discussed in the scientific literature, and it has provided information about the chemical nature of the meteoroid and the progenitor body.

北 ω-Scorpiid 流星体流：轨道和发射光谱

我们分析了 2010 年至 2012 年期间北 ω-Scorpiid 流星雨的活动。为此，我们采用了一系列部署在西班牙不同天文台的低照度 CCD 摄像机和光谱仪。根据我们的调查结果，获得了其中 11 次流星事件的大气轨迹和辐射位置。还计算了祖流星体的抗拉强度和轨道参数。计算出的轨道数据和这些流星体在大气中的行为与该流的小行星起源一致。此外，我们讨论了为这些流星之一记录的独特发射光谱。据我们所知，这是科学文献中讨论的第一个 North ω-Scorpiid 光谱，
