TITLE: GCN CIRCULAR NUMBER: 44304 SUBJECT: GOTO26djh/AT2026jpw transient: SAO RAS optical observations DATE: 26/04/16 00:39:58 GMT FROM: Alexander Moskvitin at SAO RAS <mosk@sao.ru> 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.
