Following the detection of LXT 240402A by Leia (Xu et al. GCN 36016) and FXT on board Einstein Probe (Jia et al. GCN 36022) ,
we use Antarctic Survey Telescope 3-3 at YaoAn Astronomy Observation Station (China, Yunnan) for follow-up.
Our observation started on 2024-04-03T16:28:21.084 .
No new optical source was detected within the error box (Jia et al. GCN 36022) down to 22.1 mag in the coadd image (total 60x180s, g-band).
Our non-detection is consistent with the results from the GWAC-F50A (Xin et al., GCN 36018), MASTER (Lipunov et al. GCN 36019) limits.
We thank the staff at YaoAn Astronomy Observation Station for their excellent support.
