abstract = {Since 2005, the SPanish Fireball
and 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 limiting
magnitude [1,2]. One important goal of our network is
the study of the meteoroid physico-chemical properties
from 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 photometric
patterns that are reflecting important properties of the
incoming meteoroids [3], but we are not yet fully un-
derstanding such patterns. Besides, we are also trying
to identify the main sources of large bolides to the
Earth. As a consequence of the SPMN monitoring ef-
fort, valuable trajectory and orbital data of meteors and
fireballs is being obtained [4-6]. During 2007 several
poorly-known meteoroid streams associated with com-
ets were crossed by the Earth. We describe here unex-
pected fireball activity, but focusing in low-velocity
cometary streams. Particularly, we describe some me-
teor outbursts and fireball events recorded by the
SPMN during 2006-2007 that would be important de-
livery sources of Interplanetary Dust Particles (IDPs).
We try to encourage setting up future IDP campaigns
for collecting cometary particles in the upper atmos-
phere. By knowing the most important and favourable
sources of cometary particles, and the dates of the en-
counters with dense dust trails, such missions would
be prepared in time for being successful.},
