  The first well-localized short-duration gamma ray bursts (GRBs), GRB 050509b,
GRB 050709 and GRB 050724, could have been the narrowly beamed initial spike of
a burst/hyper flare of soft gamma ray repeaters (SGRs) in host galaxies at
cosmological distances. Such bursts are expected if SGRs are young hyperstars,
i.e. neutron stars where a considerable fraction of their neutrons have
converted to hyperons and/or strange quark matter.
