A. S. Moskvitin, O. I. Spiridonova and V. V. Vlasyuk (SAO RAS),
report on behalf of the GRB follow-up team.
We observed the field of the GRB 240529A (Eyles-Ferris et al.
GCN 36556; Osborne et al. GCN 36557; Joshi et al. GCN 36560;
Dichiara et al. GCN 36564; Markwardt et al. GCN 36566; Tan et al.
GCN 36578) with the SAO RAS 1m telescope Zeiss-1000 equipped
with CCD-photometer. We obtained 4 x 300 sec frames in Rc band
on May 30, 23:35:04--23:56:50 UT (t_mid - T0 = 1.8663 days).
The OT (Kumar et al. GCN 36559; Fu et al. GCN 36561; Shilling et al.

Vinko et al., GCN 36577; Lim et al. GCN 36579) is clearly detected
in the stacked frame with the brightness of R = 20.02 +/- 0.10.
The magnitudes were calibrated using R2 magnitudes of nearby USNO-B1.0
stars.
