  Stars are uniform spheres, but only to first order. The way in which stellar
rotation and magnetism break this symmetry places important observational
constraints on stellar magnetic fields, and factors in the assessment of the
impact of stellar activity on exoplanet atmospheres.
  The spatial distribution of flares on the solar surface is well known to be
non-uniform, but elusive on other stars. We briefly review the techniques
available to recover the loci of stellar flares, and highlight a new method
that enables systematic flare localization directly from optical light curves.
  We provide an estimate of the number of flares we may be able to localize
with the Transiting Exoplanet Survey Satellite (TESS), and show that it is
consistent with the results obtained from the first full sky scan of the
mission. We suggest that non-uniform flare latitude distributions need to be
taken into account in accurate assessments of exoplanet habitability.
