AB Since 2005, the SPanish Fireballand Meteor Network (SPMN) is continuously monitor-ing meteor activity by using all-sky CCD and medium-field video cameras up to +3 to +4 meteor limitingmagnitude [1,2]. One important goal of our network isthe study of the meteoroid physico-chemical propertiesfrom multiple station data, together with meteor spec-tra. It is well known that the ablation behavior of me-teors in the Earth’s atmosphere shows photometricpatterns that are reflecting important properties of theincoming meteoroids [3], but we are not yet fully un-derstanding such patterns. Besides, we are also tryingto identify the main sources of large bolides to theEarth. As a consequence of the SPMN monitoring ef-fort, valuable trajectory and orbital data of meteors andfireballs is being obtained [4-6]. During 2007 severalpoorly-known meteoroid streams associated with com-ets were crossed by the Earth. We describe here unex-pected fireball activity, but focusing in low-velocitycometary streams. Particularly, we describe some me-teor outbursts and fireball events recorded by theSPMN during 2006-2007 that would be important de-livery sources of Interplanetary Dust Particles (IDPs).We try to encourage setting up future IDP campaignsfor collecting cometary particles in the upper atmos-phere. By knowing the most important and favourablesources of cometary particles, and the dates of the en-counters with dense dust trails, such missions wouldbe prepared in time for being successful.
