TITLE: GCN CIRCULAR NUMBER: 20058 SUBJECT: GRB 161014A: refined analysis of TSHAO optical observations DATE: 16/10/16 15:59:49 GMT FROM: Alexei Pozanenko at IKI, Moscow E. Mazaeva (IKI), A. Kusakin (Fesenkov Astrophysical Institute), I. Reva (Fesenkov Astrophysical Institute), A. Volnova (IKI), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of GRB 161014A (Racusin et al., GCN 20035) with Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory. We obtained several images in R filter starting on Oct. 14 (UT) 13:48:35. Preliminary light curve of the afterglow (Morita et al., GCN 20036; Guidorzi et al., GCN 20037; Xin et al., GCN 20038; Nakaoka et al., GCN 20039; Mazaeva et al., GCN 20042; Heintz et al., GCN 20044) can be found at http://grb.rssi.ru/GRB161014A/GRB161014A_TSHAO_LC.png Photometry is based on nearby SDSS-DR9 stars used in GCN 20042 (Mazaeva et al.)
