J. An, X. Liu, Z.P. Zhu, S.Q. Jiang, S.Y. Fu, T.H. Lu, D. Xu (NAOC), J.Z. Liu (XAO) report on behalf of a large collaboration:
We observed the field of GRB 240529A by Swift (Eyles-Ferris et al. GCN 36556) using the 50cm-B, 50cm-C, 100cm-C telescopes (50B,50C,100C) of the JinShan project located at Altay, Xinjiang, China.
Observations were carried out between 16:14:18 UT and 17:55:39 UT on 2024-05-29 in the g, r, i, and z filters. The previously reported optical afterglow, e.g., by Swift/UVOT (Eyles-Ferris et al. GCN 36556; Shilling et al., GCN 36562) was clearly detected in our images.
Photometric results are reported as follows
T-T0(d) | Filter | Mag | MagErr
---------------------------------
0.5639 | g | 19.76 | 0.18
0.5691 | r | 18.56 | 0.06
0.5639 | i | 17.80 | 0.05
0.6037 | z | 17.65 | 0.06
calibrated with nearby PanSTARRS stars and not corrected for Galactic extinction.
Furthers observations have also been done by JinShan.
We acknowledge the excellent support from S.W Luo, M.M. Yang, Z. K. Feng, and L.F. Huo for enabling these observations.
