Abstract: | We study an N=1 two-dimensional non-linear sigma model with boundaries representing, e.g., a gauge fixed open string. We describe the full
set of boundary conditions compatible with N=1 superconformal symmetry. The problem is analyzed in two different ways: by studying requirements for invariance of the
action, and by studying the conserved supercurrent. We present the target space interpretation of these results, and identify
the appearance of partially integrable almost product structures.
