L. Izzo, D. A. Kann (both HETH/IAA-CSIC), J. P. U. Fynbo (DARK), A. J.
Levan (U. Warwick), and N. R. Tanvir (U. Leicester) note on behalf of the
Stargate Consortium:

The XRT position of GRB 171205A (V. D'Elia et al. GCN #22177) contains a
bright spiral galaxy 2MASX J11093966-1235116 which lies at z = 0.037
according to SIMBAD (6df Galaxy Catalog).

The combination of a BAT image trigger, a bright XRT afterglow and lack of
a bright optical afterglow may indicate a source similar to XRFs 060218
and 100316D.

Multiwavelength follow-up is encouraged.
