Deng(NAOC) report: We began to observe GRB 210205A (Dichiaraet al., GCN 29397) with Xinglong GWAC-F60A telescope, China, at 11:13:26 (UT), 5th. Feb. 2021, about 129 sec after the burst. A series of R, I, and B band images were obtained. Preliminary analysis shows that no any new optical source are found in single images within the XRT errorbox (Dichiaraet al., GCN 29397). The 3 sigma upper limit is about 17.3 mag in R band at the mean time of 134 sec after the burst, calibrated to the USNO B1.0 catalog.
