We observed Swift GRB 210905A (Sonbas, et al., GCN 30765) with the
Dark Energy Camera (DECam) at Cerro Tololo Inter-American Observatory.
We performed 3x60s exposures with the i filter on September 5, from
04:46:10 to 04:50:09 UT.

We make a marginal detection of a source at the position reported by
Strausbaugh et al. (GCN 30769) with i=23.6. This measurement is not
corrected for galactic extinction.
