A. S. Moskvitin and O. I. Spiridonova (SAO RAS), report
on behalf of the GRB follow-up team.

We observed the field of GRB 241029A (Fermi GBM team, GCN 37932;
Schanne et al., GCN 37934; Wang et al., GCN 37935; Myers and Godwin,
GCN 37945; Bernardini et al., GCN 37946) with the 1-m telescope
of SAO RAS equipped with the CCD-photometer. We obtained 6 x 300 sec.
images in Rc band on October 29, 18:39:32--19:13:23 UT (16.6079 hours
after the burst).

The OT (Jiang et al., GCNs 37937, 37940; Lin et al., GCN 37939;
Francile et al., GCN 37941; Ackley et al., 37943; Odeh and Guessoum,
GCN 37944; Adami et al., GCN 37948; Fernandez et al., GCN 37950)
is clearly detected in our stacked
frame with the brightness of R = 20.98 +/- 0.05 (R_lim = 23.0).
This preliminary photometry is based on nearby SDSS stars (magnitudes
converted with Lupton 2005 equations) and not corrected for the Galaxy
extinction.
