AB The κ-Cygnids (KCG) were firstobserved about 150 years ago [1]. The activity periodof this annual minor shower extends from August 3 toAugust 31, peaking on August 18 with a ZenithalHourly Rate (ZHR) of about 2.3±0.4 [2, 3]. Because ofthe duration of activity and the associated spread in thelongitude of the nodes, Jenniskens suggested that theKCG stream might be old [2]. However, the analysisof the outbursts experienced in 1997 and 2007 [4, 5]suggested an opposite scenario. Besides, observationssupport the hypothesis that the formation of this meteoroidstream is a consequence of the fragmentation ofa comet nucleus [5]. This disruptive process couldhave proceeded as a cascade, where the break up of theprogenitor body leaded to produce small remnants,some fully disintegrated into different clumps of particlesand other remained as dormant objects such as2008ED69, 2001MG1 and 2004LA12 which are nowobserved as near-Earth asteroids. In this work we analyzea fireball produced by a meteoroid belonging tothe KCG stream on August 2012. Its emission spectrumwas also recorded.
