  We construct monopoles in any asymptotically conical (AC) $3$-manifold $X$
with $b^2(X)=0$. For sufficiently large mass, our construction covers an open
set in the moduli space of monopoles. We also give a more general construction
of Dirac monopoles in any AC manifold, which may be useful for generalizing our
result to the case when $b^2(X) \neq 0$.
