In GCN 21511 (an update to GCN 21508) we reported the identification of a neutrino candidate coincident with preliminary LIGO GW skymaps using only LHO data (GCN 21509), and Fermi GBM's preliminary skymaps (GCN 21506). This neutrino candidate is *not in the 90% credible region of the latest GW skymap* incorporating LHO, LLO, and Virgo data (GCN 21513).

The updated joint GW/High Energy Neutrino skymap is available on GraceDB at <https://gracedb.ligo.org/apiweb/events/G298048/files/coinc_skymap_initial_icecube.png,2>. A JSON-formatted list of the temporally coincident neutrinos included in the joint plot is available at <https://gracedb.ligo.org/apiweb/events/G298048/files/IceCubeNeutrinoList.json,0>.
