S.Q. Jiang, S.Y. Fu, Z.P. Zhu, X. Liu, T.H. Lu, D. Xu (NAOC) report:

We observed the field of ZTF23aaoohpy/AT2023lcr (Swain et al., GCN 34022) using the 2.16m telescope located at Xinglong, Hebei, China, equipped with the BFOSC camera. Observations started at 12:39:19 UT on 2023-06-20, i.e., 2.47 day after the T_GOTO=2023-06-18 01:27:41 (Gompertz et al., GCN34023), and 8x300 s frames were obtained in the R-band.

The  previously reported optical transient (e.g., Swain et al., GCN 34022, Gompertz et al., GCN34023, Kumar et al., GCN34025, Adami et al., GCN34030, Perley et al., GCN34031) is detected in our coadded image with m(R) = 21.34 +/- 0.14 at 60115.5432 (MJD), calibrated with the nearby Pan-STARRS field.

We thank the great support of the Xinglong-2.16m staff.
