We report the observations for the GRB191122A (B. Sbarufatti et al., GCN Circ 26269).
We use the 80cm telescope of CHanging Event Survey at the YaoAn observation station(101.1811E, 25.528N) in Yunnan Province, China.
Our observation starts at 13:48:57 UT and ends at 13:54:24 UT Nov 22, 2019, with five exposure 60 seconds in white filter.
We do not detect any candidate sources in the combined image in the enhanced XRT position error region to a 5 sigma limit at 18.31 generated from G band magnitude in Gaia DR2 .
