  In this note we construct a solution of six-dimensional $F(4)$ gauged
supergravity using $AdS_2\times S^3$ warped over an interval as an ansatz. The
solution is completely regular, preserves eight of the sixteen supersymmetries
of the $AdS_6$ vacuum and is a holographic realization of a line defect in a
dual five-dimensional theory. We calculate the expectation value of the defect
and the one-point function of the stress tensor in the presence of the defect
using holographic renormalization.
