Using the CALET Gamma-Ray Burst Monitor (CGBM) event data and
publicly available INTEGRAl-SPI-ACS light curve data we have triangulated
the short GRB 200805A (Shimizu et al., GCN Circ. 28217)
to a preliminary CGBM-SPI-ACS annulus centered at
RA(J2000)=57.359 deg (03h 49m 26s) Dec(J2000)=-49.453 deg (-49d 27' 10"),
whose radius is 37.65(-5.06,+4.54) deg (3 sigma).

The portion of the annulus within 69.8 deg from
RA, Dec(J2000) = 315.5 deg, -33.3 deg was below the horizon for CALET.

The CALET data used in this analysis are provided by
the Waseda CALET Operation Center located at the Waseda University.
