TITLE: GCN CIRCULAR NUMBER: 34309 SUBJECT: GRB 230723A: SPT-3G millimeter-band transient event inconsistent with IPN position DATE: 23/08/01 20:16:17 GMT FROM: Sam Guns at S Pole Telescope & UC Berkeley S. Guns (UC Berkeley) on behalf of the South Pole Telescope Collaboration: In light of the updated error box provided by IPN, the millimeter-band transient event reported by the South Pole Telescope in GCN #34301 is no longer spatially consistent with GRB 230723A (Fermi GBM, GCN #34232; IPN, GCN #34258). The event remains an unexplained, short-duration millimeter-band transient not obviously associated with any known galactic source.
