TITLE: GCN CIRCULAR NUMBER: 30829 SUBJECT: GRB 210912A: Host-galaxy candidate in PanSTARRS DATE: 21/09/12 18:48:08 GMT FROM: Alexander Kann at IAA-CSIC <kann@iaa.es> D. A. Kann (HETH/IAA-CSIC) reports: At the afterglow position (Hu et al., GCN #30823, see also Pankov et al., GCN #30825) of the Swift GRB 210912A (Troja et al., GCN #30820), an object is visible in Pan-STARRS pre-imaging at position (J2000): RA = 129.89171813 Dec. = +79.22157927 in agreement with the position given by Hu et al., GCN #30823, with magnitudes: g' = 23.19 +/- 0.23 mag, r' = 23.09 +/- 0.36 mag, i' = 22.48 +/- 0.13 mag, z' = 22.43 +/- 0.25 mag. It is undetected in Y. We suggest this object to be the host galaxy of GRB 210912A. This may be indicative that this is a low-redshift event which may be followed by a detectable supernova. Further follow-up despite the very northerly position is warranted.
