Romanov | [I have determined that AT 2023yph is a star #4631003097698452224 from the Gaia DR3.] I observed the field of GRB 231129C (Fermi GBM Team, GCN Circ. 35217) near the MAXI (GCN Circ. 35223) sky region using remote telescope T72 (0.51-m f/6.8 Corrected Dall-Kirkham + CCD) of iTelescope.Net in Deep Sky Chile at Rio Hurtado Valley, Chile. 9 images (with exposures 300 seconds, BINx1) were obtained with Ic filter with midtime 02:27 UT. I detected an uncataloged source with position 00 49 17.780 -81 29 45.83 and measured its brightness near +18 mag. Magnitude was not corrected for Galactic extinction. I am guessing this is an optical afterglow of GRB 231129C. | 2023TNSTR3105....1R | Y |

I did not have access to a computer to check in time that this object was a star with a hight proper motion. I initially compared my images with archival images from the DSS Plate Finder, but now I have determined that AT 2023yph is a star #4631003097698452224 from the Gaia DR3.
