AB We have analysed the meteor activity associated with meteoroids of fresh dust trails of Comet209P/LINEAR, which produced an outburst of the Camelopardalid meteor shower (IAU code#451, CAM) in 2014 May.With this aim, we have employed an array of high-sensitivity CCDvideo devices and spectrographs deployed at 10 meteor observing stations in Spain in theframework of the Spanish Meteor Network. Additional meteoroid flux data were obtained bymeans of two forward-scatter radio systems. The observed peak zenithal hourly rate was muchlower than expected, of around 20 meteors h−1. Despite of the small meteor flux in the opticalrange, we have obtained precise atmospheric trajectory, radiant and orbital information for 11meteor and fireball events associated with this stream. The ablation behaviour and low tensilestrength calculated for these particles reveal that Camelopardalid meteoroids are very fragile,mostly pristine aggregates with strength similar to that of the Orionids and the Leonids. Themineral grains seem to be glued together by a volatile phase. We also present and discuss twounique emission spectra produced by two Camelopardalid bright meteors. These suggest anon-chondritic nature for these particles, which exhibit Fe depletion in their composition.
