TITLE: GCN CIRCULAR NUMBER: 19614 SUBJECT: GRB 160623A: SAO RAS optical observations DATE: 16/06/28 17:39:34 GMT FROM: Moskvitin Alexander at SAO RAS A. Moskvitin (SAO RAS, Russia) report on behalf of the larger team. We observed the field of GRB160623A (Vianello et al., GCNC #19553; Mailyan et al., GCNC #19555) with the 1-meter telescope Zeiss-1000 of SAO RAS on June, 27.884 (4.676 days after the trigger). A set of 8 x 300 sec. frames in Rc band were obtained. The OT (coordinates reported by Pozanenko et al., GCNC #19561) is clearly visible in the stacked image as the object with the brightness R = 21.7 +/- 0.2. This estimation is based on the USNO-B1 stars described by Mazaeva et al. (GCNC #19574). The finding chart can be found at ftp://ftp.sao.ru/pub/grb/GRB160623A/GRB160623A_z1000.jpg
