The phi-Bootids is a minor meteor
shower whose activity period extends from April, 4 to
May, 15, with a maximum peak around May, 2. An
asteroidal origin has been postulated for the phi-Bootid
meteoroid stream, although its parent body remains
unknown [1]. Thus, additional observations during the
above-mentioned activity period may provide helpful
information to improve our knowledge about this
stream. Here we present here the preliminary analysis
of a sporadic double-station phi-Bootid fireball recorded
by us on May 10, 2011. It was recorded together
with its emission spectrum in the framework of
the continuous spectroscopic campaign developed by
the SPanish Meteor Network (SPMN). From this
analysis we have inferred information about its atmospheric
trajectory and radiant, but also about some
physico-chemical properties of the corresponding meteoroid,
such as tensile strength and chemical composition.
