A. S. Moskvitin and O. I. Spiridonova (SAO RAS)
report on behalf of GRB follow-up team.

We observed the field of the fast-fading transient GOTO26djh/AT2026jpw
(O'Neill et al., GCN 44301) with the Zeiss-1000 1m telescope
of the SAO RAS on April 15/16 night. We obtained two series of images
in Rc band.

The OT (O'Neill et al., GCN 44301; Corcoran et al., GCN 44303) is clearly
detected in the stacked images with the following brightness.
