abstract = {The parent body of the Draconid
meteoroid stream is the short period comet
21P/Giacobini-Zinner. This cometary debris gives rise
to an annual display of meteors from about October 6
to October 10, with a maximum activity around Octo-
ber 8. Although the Draconids is a minor meteor
shower, 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 of
Earth on October 8, 2011 with different dust trails
ejected by comet 21P/Giacobini-Zinner in the late 19th
and early 20th century. According to this, an outburst
with an activity of several hundred meteors per hour
was expected [2, 3]. The SPanish Meteor Network
(SPMN) joined the international organised with the
aim to study this outburst. Thus, some of the meteor
observing stations operated by the SPMN setup addi-
tional high-sensitivity CCD video cameras in order to
allow for a better coverage of this event. Besides, the
Draconid meteoroids are known to be very fragile [2],
and accurate data are fundamental in order to reach a
better understanding about the physico-chemical prop-
erties of these particles. Thus, some of these cameras
had attached holographic diffraction gratings (1000
lines/mm) in order to obtain the emission spectrum
produced during the ablation of the Draconid meteor-
oids in the atmosphere. The moon, with a phase of
about 91%, interfered with the observation, but despite
this, multi-station meteors as faint as mag. +1/+2 could
be recorded together with some fireballs. In this con-
text, we present here the anal
ysis of an extraordinarily
bright Draconid event (mag. -10.5) recorded together
with its spectrum during the 2011 Draconid outburst},
