AB By using high-resolution low-scan-rate all-sky CCD cameras, the SPanish Meteor Network(SPMN) detected an outburst of Orionid meteors associated with comet 1P/Halley on 2006October 20–21. This detection was made possible due to the operational concept of the SPMNthat involves continuous monitoring of meteor activity throughout the year. Accurate heliocentricorbits have been obtained for three meteors imaged simultaneously from two stationsduring the outburst. Additional astrometry of 33 single-station meteors indicates that the activitywas produced from a conspicuous geocentric radiant located at α = 92.◦ 2 ± 0.◦ 5 andδ = +15.◦ 4 ± 0.◦ 6 which is similar to the radiant observed during the 1993 Orionid outburstdespite the fact that the last one peaked on a different date. The radiant position obtained bythe SPMN is consistent with that derived from digital pictures taken a few hours before fromAnkara (Turkey). The extent of the outburst (a background of bright meteors was observedover several days), its absence in other years, and the orbital period of the three Orionid orbitssuggest that the outburst could be produced by meteoroids trapped in resonances with Jupiterbut additional data are required. The SPMN’s continuous coverage of meteor activity allowedthe identification of the main sources of meteors during 2006 October: mostly due to theOrionid stream, the two branches of the Taurid stream associated with comet 2P/Encke, andthe δ Aurigids. Surprisingly, once a detailed analysis of the double-station video meteors wascompleted, some additional minor stream activity was discovered, that is, the ν Aurigids. Inconsequence, we also present two accurate orbits of this unexpected, but previously identified,minor shower.
