AB The parent body of the Draconidmeteoroid stream is the short period comet21P/Giacobini-Zinner. This cometary debris gives riseto an annual display of meteors from about October 6to October 10, with a maximum activity around Octo-ber 8. Although the Draconids is a minor meteorshower, sometimes it has produced brief but spectacu-lar meteor storms. Two of these storms took place dur-ing last century, in 1933 and 1946 [1].Several researchers predicted the encounter ofEarth on October 8, 2011 with different dust trailsejected by comet 21P/Giacobini-Zinner in the late 19thand early 20th century. According to this, an outburstwith an activity of several hundred meteors per hourwas expected [2, 3]. The SPanish Meteor Network(SPMN) joined the international organised with theaim to study this outburst. Thus, some of the meteorobserving stations operated by the SPMN setup addi-tional high-sensitivity CCD video cameras in order toallow for a better coverage of this event. Besides, theDraconid meteoroids are known to be very fragile [2],and accurate data are fundamental in order to reach abetter understanding about the physico-chemical prop-erties of these particles. Thus, some of these camerashad attached holographic diffraction gratings (1000lines/mm) in order to obtain the emission spectrumproduced during the ablation of the Draconid meteor-oids in the atmosphere. The moon, with a phase ofabout 91%, interfered with the observation, but despitethis, multi-station meteors as faint as mag. +1/+2 couldbe recorded together with some fireballs. In this con-text, we present here the analysis of an extraordinarilybright Draconid event (mag. -10.5) recorded togetherwith its spectrum during the 2011 Draconid outburst
