  Jupiter-family comet 15P/Finlay has been reportedly quiet in activity for
over a century but has harbored two outbursts during its 2014/2015 perihelion
passage. Here we present an analysis of these two outbursts using a set of
cometary observations. The outbursts took place between 2014 Dec. 15.4--16.0 UT
and 2015 Jan. 15.5--16.0 UT as constrained by ground-based and spacecraft
observations. We find a characteristic ejection speed of $V_0=300$ to $650
\mathrm{m \cdot s^{-1}}$ for the ejecta of the first outburst and $V_0=550$ to
$750 \mathrm{m \cdot s^{-1}}$ for that of the second outburst using a Monte
Carlo dust model. The mass of the ejecta is calculated to be $M_\mathrm{d}=2$
to $3\times10^5 \mathrm{kg}$ for the first outburst and $M_\mathrm{d}=4$ to
$5\times10^5 \mathrm{kg}$ for the second outburst, corresponds to less than
$10^{-7}$ of the nucleus mass. The specific energy of the two outbursts is
found to be $0.3$ to $2\times10^5 \mathrm{J \cdot kg^{-1}}$. We also revisit
the long-standing puzzle of the non-detection of the hypothetical Finlayid
meteor shower by performing a cued search using the 13-year data from the
Canadian Meteor Orbit Radar, which does not reveal any positives. The Earth
will pass the 2014/2015 outburst ejecta around 2021 Oct. 6 at 22 h UT to Oct. 7
at 1 h UT, with a chance for some significant meteor activity in the radio
range, which may provide further clues to the Finlayid puzzle. A southerly
radiant in the constellation of Ara will favor the observers in the southern
tip of Africa.
