Query: The globular cluster system of the isolated elliptical NGC 6411: An old
  system in an intermediate-age galaxy?   We present a photometric study of the isolated elliptical NGC 6411 and its
globular cluster (GC) system, based on Gemini/GMOS g', r', i' photometry. This
galaxy has been the host of a SNIa. Spectral studies indicate an
intermediate-age and very metal-rich stellar population in its inner region.
The extent of the globular cluster system is about 65 kpc. Its population
contains $700\pm45$ members, implying a rather poor system, as normally found
for isolated ellipticals. The colour bimodality and luminosity distribution are
typical of old GC systems. An excess of bright GCs with intermediate colours
might evidence an intermediate-age merger, but their colours indicate an older
event than ages derived from spectroscopic studies of the diffuse light of the
galaxy.
