AB The omicron Draconids were firstobserved by Denning in the 19th Century [1]. The activitywas, however, modest, with a zenithal hourlyrate (ZHR) of about 10–12. Denning [2] also reportedobservations in 1929 but in neither case was an orbitgiven, only a radiant position (RA ~271º, Dec. ~60º).However, for a considerable time after Denning’s observations,no records of any activity exist. Whetherthis is due to a lack of observers at the pertinent time(early July and thus close to the longest day and alsoclose to the activity period of the delta Aquariids andobservers may have preferred to study those) or anintrinsic lack of activity from the Omicron Draconidsis not clear. The next record appears to be by Cook etal. [3] reporting on the work of the Harvard MeteorProject in the 1950s. In that paper they also suggestedthat the formation of the stream was associated withthe disintegration of the nucleus of comet C/1919 Q2Metcalf. In fact, our team recorded in 2008 a mag. -18omicron Draconid fireball which was linked to thiscomet [4]. Here we present the analysis of a doublestationomicron-Draconid fireball recorded in theframework of our continuous fireball monitoring andspectroscopic campaigns in July 2007. The uniquespectrum obtained for a member of this stream hasprovides helpful information about the chemical natureof meteoroids in the omicron-Draconid stream.
